notebook crashes on battery with particular wlan or other pcie devices enabled dell vostro 3700

[aspera]

If I start my Dell Vostro 3700 in 10.10 without Power AC adapter Ubuntu crashes after a shot while (max 2minutes).

Ubuntu does not crash, if WLAN is switched off or is not present.
If I have a connection over LAN it does not crash, too.
It crash, if I use my SmartPhone as modem.

This does not happen with a 10.04.1 Live CD.

It does not crash in Windows.

WORKAROUND: Install the package "laptop-mode-tools". The packages acpi-support and pm-utils will be removed. Open file:
/etc/default/acpi-support

write or copy the following lines at the end:
# Switch to laptop-mode on battery power - off by default as it causes odd
# Hangs on some machines
ENABLE_LAPTOP_MODE = true

Then change the Laptop-Mode on Battery in:
/etc/laptop-mode/laptop-mode.conf

to 1:
ENABLE_LAPTOP_MODE_ON_BATTERY = 1

Restart the computer and it should work.

[aspera (aspera10)]

Hello,

now I tried the new final released live-cd and I've got the same problem.
Now I'll run the apport collect, but I can't do it on battery, cause I have not enough time before Ubuntu crashes.

 Is this enough for You?

Thanks

Hello again,

I still found following:

Ubuntu does not crash, if WLAN is switched off or is not present.
If I have a connection over LAN it does not crash, too.

It crash, if I use my SmartPhone as modem.

Hope it is important.

[Christian (c-pradelli)]

I have the same problem (freeze on battery powered) in my new Dell Vostro 3700 i7
I partially solved unchecking, in Power Management, the checkbox that reduce hdd speed when possible.
But now it freeze when battery level is critically low.
I think that this problem is all about Power Managent.
It really make maverick unusable on this laptop

[aspera (aspera10)]

Hello Vostro 3700 - Users and specially Christian,

It's really unpossible to work with this bug. After a long search I have found a workaround that works at least for me. But attention: You are loosing the suspend and hybernate-functions.
Install the package "laptop-mode-tools". The packages acpi-support and pm-utils will be removed.

Then, with using sudo in the

/etc/default/acpi-support

write or copy the following lines at the end:

# Switch to laptop-mode on battery power - off by default as it causes odd
# Hangs on some machines
ENABLE_LAPTOP_MODE = true

Then change the Laptop-Mode on Battery with sudo in the /etc/laptop-mode/laptop-mode.conf to 1
like here:

ENABLE_LAPTOP_MODE_ON_BATTERY = 1

Restart the computer and it should work. If you speak German so you can find under

http://wiki.ubuntuusers.de/laptop-mode-utils

a detailed description.

I hope you could understand my english

Good luck

aspera

[Christian (c-pradelli)]

Hello Aspera,

My recommendation is go back to Lucid (I already did it).
It's not safe to work in this manner. Also Maveric doesn't introduce any new feature that justify this madness.

[Andreas Noteng (andreas-noteng)]

Settin importance high on Fabio Marconi's request

[Christian (c-pradelli)]

aspera, are you sure that "power or thermal limit exceeded" is related to this bug?

[aspera (aspera10)]

That wasn`t my analysis. I have passed only the desired files. I think Fabio has the necessary knowledge to analyze such files.
 I think it is not a thermal problem...

[Christian (c-pradelli)]

I did the comment because I see that in the bug title.

[Fabio Marconi (fabiomarconi)]

@Christian
Can you please attach these files
/var/log/syslog
/var/log/kern.log
Fabio

@ aspera

from your syslog:
Oct 10 16:05:13 edwin kernel: [ 4353.912270] intel ips 0000:00:1f.6: MCP power or thermal limit exceeded

                                                                                                                        ^^^ ^^^^^^^^^^^

[Christian (c-pradelli)]

@Fabio,
I removed Maveric form my Laptop and now I have Lucid instaled. I will try to reproduce the bug with the live CD asap.

[alexpennos (pennos)]

Also affects me...running 10.10 on a dell studio1557 w corei7.

[Fabio Marconi (fabiomarconi)]

Can you follow this procedure:

[aspera (aspera10)]

Now, I tested "Linux Mint Julia" wich is based on Ubuntu 10.10. All things are working fine. There are no problems!

aspera

[aspera (aspera10)]

I'm sorry, but I was a little bit to fast. After I attached Linux Mint Julia to wlan and USB-Memory, it crashed after the Filetransfer began immediately also.

But I found finally a workaround, which I have tested the last 2 days:

I deinstalled the pm-utils 1.4 with synaptic. Download the package pm-utils 1.3.0-1ubuntu1_all_deb from

"http://packages.ubuntu.com/de/lucid/all/pm-utils/download"

and installed it.

Now it workes fine and all functions remain in the best way.

In my opinion the error lies in the current pm-utils package. But I am only a completely normal user and not a programmer!

Would anybody test it too and write a coment?

Thanks

aspera

[Eduardo Figarola (lalo-diabulux)]

Hi, everybody!

I have the same issue... When I try to install ubuntu 10.10 x64 I have to use a little tricks to get it! And it was because the bug "intel ips" So I solved using the live cd and adding to the etc/modprobe.d/blacklist.conf the following line "blacklist intel_ips" and in this way I was able to install ubuntu...

Now I have the same problem that you are describing, when I use my laptop in battery mode it hang in a black screen and I have to hard reset, as information my laptop is a Core i7 Gateway ID59C and I can work perfectly with my battery in Win 7. Also I can work perfectly with only the AC Adapter in ubuntu, but it is not so funny.

I would love to help to solve this problem but I'm a beginner user in linux, so I could be useful to try anything you request.

Finally, I haven't done anything that you're advicing.

I'm sorry for my bad english, I'm not a native speaker.

Thanks for the time.

[alexpennos (pennos)]

@aspera
The solution that aspera suggested on #37 worked perfectly for me. I now have one more question, the update manager wants to download a newer version of pm-utils 1.4-1 (i think). Should i avoid this?

[aspera (aspera10)]

@alexpennos

do not download the newer version - you'll get the same problems like before. With Synaptik you can
force pm-utils 1.3.0 package.

On my laptop, the workaround still works fine.

aspera

[A.Ilusin (a-ai)]

I migrated to Gentoo because of this problem. On gentoo pm-utils-1.4.1 does not hang.

[gibbylinks (gibbylinks)]

Hi I can confirm have the same problem. I swapped my OEM network card for an Intel 4695AGN and machine would crash under battery power, unless wi-fi turned off.

Downgrading pm-utils to 1.3.0 has solved it for me.

Running 10.10 with 2.3.36 kernel.

[A.Ilusin (a-ai)]

In my case, on a laptop Dell Vostro 1510 hung script from the package pm-utils 1.4.1-r1, namely pm-powersave. I copied all the scripts from /usr/lib/pm-utils/power.d in /etc/pm/power.d and withdrew from all the execute bit - thus blocking scripts from /usr/lib/pm-utils/power.d . Then removing them one by one found that the computer hangs in the performance pcie_aspm. I will try to examine the issue more deeply, if possible.

[Miroslav (dzundam-deactivatedaccount)]

I can reproduce the bug behaviour by running:

echo powersave > /sys/module/pcie_aspm/parameters/policy

That's exactly what /usr/lib/pm-utils/power.d/pcie_aspm does
when the system runs on battery.

I'm not programmer, I'm not going to dig into kernel sources for
now, but I think the primary problem lies in dodgy ACPI BIOSes
of our systems (too many Dell systems are affected).

The temporary workaround for the 10.10 would be to remove
pcie_aspm script from pm-utils package.

People are welcomed for testing!

[Clayton Dillard (claytondillard)]

I moved to kernel version 2.6.36-020636-generic #201010210905 several days ago and have done many suspend/resume and dock/undock in my HP 8530W notebook without any issues with system lockup or freeze. I also moved away from using the proprietary Nvidia driver in favor of Nouvea but doubt this has any affect on the issue.

[Galois Ghost (galoisghost)]

I can confirm that whilst running:

echo powersave > /sys/module/pcie_aspm/parameters/policy

does not replicate the bug.

Commenting out the path /sys/module/pcie_aspm/parameters/policy in /usr/lib/pm-utils/power.d/pcie_aspm and rebooting stops my system from freezing.

[Miroslav (dzundam-deactivatedaccount)]

> Galois Ghost

Did you run the echo command in the root console?

If not you probably got the "Permission denied" message. You have to run it as root.

What I do:
sudo bash
echo powersave > /sys/module/pcie_aspm/parameters/policy

My system crashes sometimes after 4 second, sometimes after 20-30 seconds, sometimes even
after 1 minute, but crashes ALWAYS after I run the echo.

[spantch101 (spantch101)]

thank you aspera post #37 worked flawlessly on my k50-id im using battery right now :D

[Galois Ghost (galoisghost)]

Miroslav,

Yes I ran it in a root console, no crash after waiting 15 minutes. Yet I pull out power cord, crash occurs within a minute. With the work around there is no crash in either case.

[Miroslav (dzundam-deactivatedaccount)]

Galois Ghost,

that's very interesting.

Could you please undo your changes in your
/usr/lib/pm-utils/power.d/pcie_aspm
and then create empty file "pcie_aspm" in
/etc/pm/power.d folder with execute bit disabled?
What this does it prevents
/usr/lib/pm-utils/power.d/pcie_aspm
from running.
It's better way than to modify
/usr/lib/pm-utils/power.d/pcie_aspm,
because your changes might be lost in future
updates of pm-utils.

Please report how it works.

[Galois Ghost (galoisghost)]

Hi Miroslav,

Changes made as suggested. All is good so far, no freezes.

[Hugo Hernan Buitrago Rios (hhbuitrago)]

I can also confirm that making the changes in Comment # 50 solved the problem for me.

[gibbylinks (gibbylinks)]

Hi Post #50 failed to work for me. Having to reverted to "pm-utils_1.3.0-1ubuntu1_all.deb"

 Running Maverick 10.10 with Kernel 2.6.36-020636-generic on Dell Inspiron 1501 4gb RAM with Intel 4965 AGN wireless card.

[Miroslav (dzundam-deactivatedaccount)]

Hi gibbylinks,
I'm surprised it's not working for you because
your system is almost the same like mine (Inspiron 1501
and Vostro 1000 share the same "guts"). You even
have the same wifi card.

Could you check whether "pcie_aspm" in /etc/pm/power.d has
"rw--r--r--" permissions?

If so and your system still crashes while on battery,
could you please create another empty file "wireless" in
/etc/pm/power.d folder with permissions "rw-r--r--"?

Then run "sync" before removing the power cord to
minimize filesystem corruption.

[gibbylinks (gibbylinks)]

Hi Miroslav,

Thanks for help. I already had wireless. I've rename it "wireless.old" and made new one. I can confirm this works OK now.

Running on latest pm-utils now and working on battery power.

[markusheinzer (markus-heinzer)]

the proposed changes by comment #50 of miroslav did the job on my system (Dell Vostro 1015). thanks a lot!

[Ruben Verhack (ruben-verhack)]

Comment #50 fixed the freezing on battery for me on my dell studio 1558 (i5, ATI Radeon 5470)

[JosephWheatley (skinnyjim)]

Could someone please describe how to carry out the advice in comment #50 for newbies?

I have managed to create an empty file on the desktop with the name pcie_aspm
and then moved it to the folder
/etc/pm/power.d
with
sudo cp pcie_aspm /etc/pm/power.d

This hasn't worked.
I don't know how to disable the execute bit. Do I just uncheck the box under permissions?

[markusheinzer (markus-heinzer)]

Hi Joseph
Yes, uncheck the box. But you have to do this with admin privileges of course. For such operations I use nautilus as sudo (start it in the terminal: sudo nautilus).
I think the unchecking of the box leads to this behaviour: the system finds a file, tries to execute it instead of some standard procedure, but is then not able to execute it.

[Tao Huang (greatht)]

Another dell studio 1558 user here, I tried two different solutions found on the internet for this bug.

Solution 1: Downgrade package pm-utls from version 1.4.1-3(Maverick) to 1.3.0-1ubuntu1(Lucid)
It works well but still suffers from random freezing (Several times per day)

Solution 2 as described in comment #50:
It works for the first 30 minutes, and then freezes. I don't know for how long other 1558 users tried on their laptops.
I tried twice on mine and both froze after 25-30minutes.

So far, this has been a serious problem to the daily use of my 1558 since I need to unplug the adapter several times during
the day for meetings. And it looks like there won't be a fix for this until the next major release. I am consider rolling back to Lucid as one of my colleagues did.

[Sarah Strong (sarahstrong)]

Dell Studio 1558, Ubuntu Maverick 10.10.
I had seemingly random freezes several times a day, only when on battery. I'm almost always on wifi so it's likely the identical error condition of battery + wifi triggered it.

Downgrading pm-utils to version 1.3.0-1ubuntu1 fixed the issue for me.

[JosephWheatley (skinnyjim)]

Using Comments #50 and #54 I did the following to prevent the freezes on my Packard Bell MZ35

I created an empty file by right clicking on the desktop and choosing "Create Document" and then "Empty File"
Then I gave the file the name

pcie_aspm

I repeated this to create another empty file called

wireless

The two files were be copied to the folder /etc/pm/power.d

I started the terminal with the command ctrl-alt-T
navigated to the Desktop folder with

cd Desktop

and pasted in this command

sudo cp pcie_aspm /etc/pm/power.d

followed by

sudo cp wireless /etc/pm/power.d

Once this had been done I pulled out the power lead and found my laptop no longer crashed.
I think a restart is necessary as within an hour my computer performed a bizarre reboot that must have been caused by confusing the pm-utils
I have had no such crashes since.

[Ruben Verhack (ruben-verhack)]

@Tao
Indeed, I did not check Solution 2 for a long period, as I unplug mostly to change location and replug their again. I'm on another laptop atm. I will post back as soon as I can. Meanwhile, how come this bug hasn't got any attention yet? It makes using Ubuntu virtually impossible without a fix

[Clayton Dillard (claytondillard)]

I would also like to know why Canonical/Ubuntu isn't addressing this issue. It has been present since 10.10 was released months ago. It's severe and makes it very hard to use Ubuntu as a daily workstation. I've been running Linux as my primary OS for nearly 7 years and this is the worst bug yet. The thought of making it half way through a switch implementation and having Ubuntu crash, causing all of my time and work to be lost is disheartening.

[Miroslav (dzundam-deactivatedaccount)]

@Clayton Dilland

One of the reasons might be that this bug affects mainly (or only) Dell machines with ATI chipset.
If nobody of developers or testers has that machine, it's impossible for them to debug the bug :-(

I personally found Dell BIOSes quite dodgy, especially ACPI part, for example my Express Card slot
has no hot-plug capability under Linux, or I had issue changing LCD brightness using keyboard, etc.
I still have problem with Google Earth - unusable rendering on my Dell Vostro.

I'm running an HP 8530w and obviously it affects me. The title of this bug should be changed because it doesn't just affect Dell computers. This really sucks. Linux is great but to have a serious bug like this that affects the stability of the OS is totally unacceptable.

[Miroslav (dzundam-deactivatedaccount)]

Well, guys, I only can agree with you.

It happened for the first time to me that after
upgrade to new version of Ubuntu the system
become much less usable than with the older
version.

Maybe the Canonical should slow down and
bring only one version of Ubuntu per year.
They'll then have time for reading our bug
reports.

[Clayton Dillard (claytondillard)]

My environment is:
HP Elitebook 8530w
Nvidia Quadro FX570 w/ Cuda
Intel Wireless N 5300
Broadcom GbE NIC
Ubuntu 10.10 x86_64

These freezes/crashes result in total lockup. Power off is the only recourse. This usually happens when disconnecting the power cord, after resuming from suspend.

Scenario 1:
Working from home,
Suspend and take my notebook to the office
Dock it in the docking station and turn it on
LOCK UP

Scenario 2:
Working in the office with my notebook docked in the docking station
Nvidia settings is Twinview with my notebook monitor and an LCD screen
Disable the LCD and prepare to go home
Undock the notebook because I want to suspend and leave
LOCK UP

Scenario 3:
Wake up from suspend undocked
Crank up Chromium Browser
Scroll down a long page, like this one with all of these bug threads
LOCK UP

I am facing the same problem. I have DELL VOstro 3700 with core i7, NVIDIA, Broadcom 4313.

Earlier the system used to hang whenever I try to access wireless. I got a work around for the same by uninstalling broadcom drivers those were from Ubuntu repo, and downloaded from Broadcom website.

But the switching to battery problem is still there.

The system was shipped with 9.10, which I upgraded to 10.10. There the problem started. The system would hang within minutes of switching to battery. Then I thought of "upgrading" it further and tried to install 11.04, still no luck. I tried both 32bit and 64 bit for all these OS's (except for 9.10 64-bit).

[Titus Kleppinger (titus-kleppinger)]

Thank you sooooo much Joseph W. My Toshiba was crashing - thank you for the layman terms for us noobs.

Using Comments #50 and #54 I did the following to prevent the freezes on my Packard Bell MZ35

I created an empty file by right clicking on the desktop and choosing "Create Document" and then "Empty File"
Then I gave the file the name

pcie_aspm

I repeated this to create another empty file called

wireless

The two files were be copied to the folder /etc/pm/power.d

I started the terminal with the command ctrl-alt-T
navigated to the Desktop folder with

cd Desktop

and pasted in this command

sudo cp pcie_aspm /etc/pm/power.d

followed by

sudo cp wireless /etc/pm/power.d

Once this had been done I pulled out the power lead and found my laptop no longer crashed.
I think a restart is necessary as within an hour my computer performed a bizarre reboot that must have been caused by confusing the pm-utils
I have had no such crashes since.

I have found a work around. After implementing the suggestion by Aspera (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/656745/comments/26), the frequency of freezing has reduced a bit...

Statistically I could see that if start the system on AC and put it on battery after booting, I can avoid freezing. I dont know understand the technical aspects, but this seems to be a promising solution. Can somebody please explain me the logic?

Have you tried Miroslav's solution? Does that not work for you?

I work with the workaround in comment 37 and locked the pm-utils 1.4 for updates. It is working fine. I have no more crashes.
Maybe the solution of miroslav is the better one, but I have not tried it.

[Colin Ian King (colin-king)]

The Active State Power Management (ASPM) driver pcie_aspm in the default mode appears to be picking up the configuation from the BIOS default, which seems to be causing issues on this particular Vostro.

I suggest as a workaround disabling PCIe ASPM with the kernel parameter: pcie_aspm=off

To do so, as edit /etc/default/grub and change:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"

and re-run upgrade-grub.

If this fixes the problem, then it's most certainly a BIOS misconfiguration. Please can you verify this and let me know your results.

[Miroslav (dzundam-deactivatedaccount)]

@Colin King

First, I'm glad to see somebody from kernel team here ;-)

Second, I've tried your "pcie_aspm=off" kernel parameter.

Short answer:
-----------------
It DOES work for me. I will observe my machine and report,
if it crashed. For now, I type this message on machine running
on battery.

Long answer:
-----------------
I did undo the changes in /etc/pm/power.d from my post #50.
Then I switched off the machine.
Turned on, logged on, waited 1 minute, synced and pulled off
the power cord. System crashed after 7-8 seconds.
By doing this I verified, that the bug is still present.
So far so good.
Then I started machine again, logged in, done what post #76
wants, turned machine off.
Turned machine on, logged in, waited 1 minute, synced,
pulled power cord off the laptop and NOTHING bad has happened.

Very good, Colin.

I already expected ACPI BIOS of my Dell machine to be the suspect,
but what makes no sense to me is that I have this freezing problem
only with Intel 4965AGN WiFi card...

[Vinay (vinay-wagh)]

@Aspera,
Sorry for the delay in replying... miroslav's solution didnt work for me... In fact I had done exactly what you are saying in #75. The freezing is now reduced to almost twice/thrice a day.

But it has started another problem (I dont know whether I have messed up some other files also!!!). Also I dont know whether they are related!!!

The machine get very hot. The CPU temp goes close to 75C... I have observed that most of the freezing occurs when the temp goes very high. I am generally doing a regular work on the machine (mainly usual internet browsing (without much of java or flash) or dealing with text files.) So dont expect CPU+GPU to be over heated!

@Miroslav:

> My question is: What side effect can I expect from "pcie_aspm=off"?

PCI Express Active State Power Management (ASPM) defines a protocol for the PCI Express components in the D0 (fully on)
operating state to reduce the Link power. This is achieved by putting their Links into a low power state and informing the
other end of the link to go into a low power state too.

The Pros to using ASPM:

+ saving power, depends on your machine and devices on the PCI link, but could be a Watt or so of savings. Your mileage may vary.

Cons:
- introduces device latency
- the default mode is based on the BIOS settings, which may be wrong

One can experiment with different pcie_aspm settings, for example:

pcie_aspm=off
   - disables ASPM.
pcie_aspm=default
   - use BIOS provided ASPM settings
pcie_aspm=performance
   - disables ASPM and clock power management
pcie_aspm=powersave
   - highest power saving mode, enable ASPM and clock power management

[Miroslav (dzundam-deactivatedaccount)]

@Colin King

Thanks for you replay, I google-d a little bit
to get the understanding what's PCIE_ASPM
like and I found the explanation on the Intel
site.

I run my notebook with pcie_aspm=off parameter,
because it solves the machine crash when pulling
out the power cord.

I didn't study the kernel sources, but I'm still
curious how the kernel sets the
powersave/performance mode. It must set
some registers in hardware and the question is
are these settings chipset independent or are
they different for amd/intel/via/... ?
Are they defined in BIOS for every machine (like settings
for "default")?

In my case I have all this crashing problems only because:

1) amd chipset bug
this does not explain why my laptop doesn't crash when
using another internal pcie wifi card, only with intel

2) bios bug

3) intel wifi card hardware bug

4) intel iwlang kernel module bug

Until we know where exactly is the problem, we must
blacklist the problematic machines in pm-utils (because
pm-utils do the job of performance/powersave switching).

[Colin Ian King (colin-king)]

@Miroslav,

It may be one of several issues. So if you are willing, we can tease these out with some sanity checks. I've just read an ASPM document from http://msdn.microsoft.com/en-us/windows/hardware/gg462958.aspx and it states:

"If the BIOS indicates that the platform does not properly support ASPM, the operating system disables ASPM. This can be conveyed in the ACPI fixed ACPI description table (FADT) table IAPC_BOOT_ARCH flags by setting the PCIe ASPM Controls bit to 1."

To sanity check this, can you send me a copy of your ACPI tables using:

sudo acpidump > acpidump.txt

..and I will see what the IAPC_BOOT_ARCH flag is configured to.

Incidentally, the BIOS default basically refers to how the firmware configured the PCI config regions for your PCI-e devices - it may be that theses are mis-configured and causes the wifi card to misbehave when the kernel tries to go into a power saving state and the H/W does not support it correctly. It's hard to tell w/o some further investigation.

[Miroslav (dzundam-deactivatedaccount)]

@Colin King,

please find the acpidump attached.

[Colin Ian King (colin-king)]

@Miroslav,

Thanks for the ACPI data, it was most helpful to bring some insight.

the IA-PC boot flags does state that "PCIe ASPM is not supported":

[0x06d 0109 2] IA-PC Boot Flags (see below): 0x0000
                           Legacy Devices Supported (V2): 0x0
                      8042 present on ports 60/64 (V2): 0x0
                                            VGA Not Present (V4): 0x0
                                        MSI Not Supported (V4): 0x0
                           PCIe ASPM Not supported (V4): 0x0

and this apparently is what Windows 7 seems to follow (http://www.microsoft.com/whdc/system/bus/pci/aspm.mspx). So it appears that the Linux aspm driver is not taking this advice into consideration and hence we get the problem. Disabling ASPM via the boot option "pcie_aspm=off" hence makes sense. I will open a discussion with the Intel developers and see what they make of this.

[Colin Ian King (colin-king)]

My mistake, the bit is set to zero on your firmware, which means ASPM can be enabled by the OS, so let's ignore that for now.

[Miroslav (dzundam-deactivatedaccount)]

@Colin King

thanks for your prompt reply.

For me it still doesn't explain the fact, that the
Broadcom WiFi card (based on BCM4315 chipset)
simply works without problem.

At least we're moving somewhere.

Would it be helpfull for you if other people (with
exactly same symptoms!) posted their acpi dumps?
Just to make sure all is about the ignored
bios acpi flag.

[Colin Ian King (colin-king)]

Miroslav, perhaps it works on the Broadcom Wifi card because it can handle the link request to power it down, where as the other device cannot. From what I understand, the ASPM protocol can power down the link and where possible, devices on the link.

I wonder if pcie_aspm=performance will make it behave differently.

[Miroslav (dzundam-deactivatedaccount)]

Your post #87 appeared on my display after I posted mine (#88),
the launchpad is not good for real-time posting.

[Miroslav (dzundam-deactivatedaccount)]

@Colin

In my early troubleshooting efforts I set the performance mode
and if I recall there was no problem. When I set powersave it crashed
few seconds later.

@A.Ilusin

Have you found something suspicious in the logs after the crash?

To increase the chance having something logged press and hold
Alt+Print and keep pressing S so quickly as you can. With other
hand pull out the power cord and keep pressing S until the machine
crashes.

Then reboot and check the logs.

[Colin Ian King (colin-king)]

@Miroslav, thanks for the update. I hope to be getting access to one of these laptops in the near future to debug this a bit deeper.

[Colin Ian King (colin-king)]

@Miroslav,

Looking at the iwl driver it has a workaround for a H/W bug that addresses instability on the PCIe bus L0->L0S->L1 transitions and disables L0S. The workaround seems to check the PCI configuration as set by the firmware, hence this may a reason for the bug.

Currently I suspect the following scenario:

1. The driver can workaround a bug in the H/W, if the firmware has configured the PCI space correctly.
2. We may not have the PCI_CFG_LINK_CTRL_VAL_L1_EN bit set correctly, so the driver can't work around the H/W bug which disables L0S.
3. The link management may be then transitioning the H/W to L0S and we get into the situation where it appears the wireless H/W disappears when the link power management kicks in.
4. We see errors like "HARDWARE GONE?? INTA == 0xffffffff" which seems to confirm this.

So, can you attach the output of "sudo lspci -xxxx" so I can eyeball the config space and see if this is what is happening.

[Miroslav (dzundam-deactivatedaccount)]

Colin,
please find lspci attached.

[Colin Ian King (colin-king)]

Miroslav, sorry, one more request, can you provide output from:

sudo lspci -vvnn

Thanks.

[Miroslav (dzundam-deactivatedaccount)]

Colin, no problem.

[Mateo Burillo (mateobur)]

Colin King, I tried you solution in #76 and it seems to be working. Thanks!

The problem is that now the fans are on all the time and the laptop seems to get hotter, is this a subjective impression or it's an expected consequence of disabling PCIe ASPM?

Dell studio 1558 here, I can provide any logs you require.

[Colin Ian King (colin-king)]

@Mateo, it could be because you laptop is consuming more power, but it could be subjective. The trick is to run the machine on powertop for 10-15 minutes with and without the workaround to see the power consumption difference - it's the easiest way to check of the ASPM workaround is causing the machine to consume significantly more power or not.

[Mateo Burillo (mateobur)]

@Colin, FYI this bug is still present in 11.04

[Mateo Burillo (mateobur)]

@Colin King using Ubuntu 10.10 and with the solution of #76, after ~20 minutes of heavy CPU work (compiling) the
computers starts to run very slow and then it shuts down suddenly.

[Miroslav (dzundam-deactivatedaccount)]

@Mateo

I think your laptop overheats and shuts down (for safety reasons),
I don't think it has something to do with the PCIE active state power
management, thanks to Colin's sollution your laptop started to
work on battery but fails for other reason.

If it shuts down during heavy load, that suggests the dusty heatsink
or lack of good thermal contact between CPU/GPU/chipset and heatsink.
When I worked in Dell factory, sometimes we got faulty heatsinks
from the supplier and all the computers failed during the build test.

The laptop should never turn off itself during the heavy load,
only when the cooling areas are blocked, i.e. you forget it under
the duvet.
Otherwise it's the good reason for asking for replacement.

If your laptop gets hot during idle, you check the CPU power
management, i.e. you put the "CPU Frequency Scaling Monitor"
applet on the top tray and check what frequency your CPU runs

I suggest the "ondemand" mode.

[Wolfgang Kufner (wolfgangkufner)]

@Mateo

Indeed, I have to remove a dust cake from between fan and heat sink about every 6 month or my Acer Extensa 5630Z will not be able to run with full power for more than a few minutes.

This is a bit of a design failure as there is no easy to remove filter. Instead I have to open the main hatch (6 screws) and remove the fan, which is way more fiddly than this should be.

[Mateo Burillo (mateobur)]

@Wolfgang @Colin King @Miroslav

It's true that it shuts down whether I put the kernel parameter or not.
But I tried this on windows 7 (same machine of course), running Prime95 (a CPU stress test)
for ~1 hour and nothing happened. Again, available for any tests & logs you require.

[Miroslav (dzundam-deactivatedaccount)]

@Mateo

I must admit lack of ideas in your particular case,
need to say this thread tries to solve different
problem. Good luck.

[Wolfgang Kufner (wolfgangkufner)]

@Mateo

Since you say it shuts down with and without the pcie_aspm=off parameter it indeed looks like a different problem.

Next steps I can think of:

Make sure that Prime95 on windows 7 is running at full speed on all cores. Maybe it is running with reduced speed and that is the reason it does not overheat and shut down. In that case dust could still be the culprit.

Is it a temperature induced shutdown at all? Look at what the temperature does. Look at https://wiki.ubuntu.com/Kernel/Debugging/HighTemperatures. Bug 563815 might also offer a few hints as to where to look.

Last but not least. Make a separate bug report with ubuntu-bug linux from a terminal window. We shouldn't mix different issues. Feel free to subscribe me to your new report.

[Michele Pittoni (mpitt79)]

I have an Asus X5DID-SX058V, Intel Pentium T4400 CPU, Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01).

Before seeing this bug report I experienced this bug and I tried to troubleshoot it. I blacklisted the ath9k module and verified that the machine didn't crash. Then I tried
modprobe ath9k
and with my great surprise it worked. I was then able to work without problems until my battery finished its charge.

Don't know if this adds a useful information.

[Michele Pittoni (mpitt79)]

I removed ath9k from the blacklist and tried #76 solution: it seems to work! Thanks a lot!!

However, I'm still wondering why the bug doesn't happen when loading the module manually.

[Brent (brentcolby)]

Solution #76 is working for me as well.
Thanks for all of the time everyone. I love all of the bug-hunters!

[Galois Ghost (galoisghost)]

Finally got around to trying #76. It did not work.

First I undid changes from #50 rebooted and confirmed the freeze still occurred. I then made the changes as per #76 rebooted and the freeze was still present.

[ceg (ceg)]

@Galois:
To confirm you actually booted with pcie_aspm=off you can check the output of
"cat /proc/cmdline".

In comment #76 there is a typo, you need to run "sudo update-grub" (not upgrade-grub).

[Colin Ian King (colin-king)]

Just to add, we are actively trying to acquire some hardware so that we can debug this one further - we've not given up on this.

@Mateo, can you open a new bug, as I'm not entirely sure you issue is the same as this one. Thanks!

[Mateo Burillo (mateobur)]

@Colin and others,

After some testing in Windows and calls to dell support, I know where is my issue. My laptop's ventilation system just
can't handle the processors at 100% for more than 15 minutes. That causes linux to crash, in Windows they use the "trick" of
reducing to 58% now and then to control the heat. They say a laptop it's not supposed to be on maximum performance all the
time and that they don't consider this a malfunctioning. Thanks for all your support guys.

[Miroslav (dzundam-deactivatedaccount)]

@Colin

have you found something interesting in my log (post #98)?

[Thomas Lenarz (tommesml)]

I just would like to drop a note.

I tried comment #76 on my ASUS X51 Laptop.

However, it does not solve the problem for me, I am afraid.

Problem persists as described in my original bug-report https://bugs.launchpad.net/bugs/605967.

Please feel free to tell me if I could try out something and/or provide further information.

Thanks for all the work.

[jorgejhms (jorgejhms)]

Any hope this would be fix for Natty?

[Galois Ghost (galoisghost)]

@ceg Ah I see. when upgrade-grub failed I was running grub-mkconfig. So now I've run the correct command it works.

[szb (szb)]

Greetings,

For your information. I have a HP 6735b with Ubuntu 10.04 LTS with the same problem as described here, i.e. Ubuntu crash when going on battery (i.e. removing AC power), or on start up when on battery.

I have tried comment #76 :

<<<
in /etc/default/grub change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"
and run "sudo update-grub"
>>>

It didn't work for me : Ubuntu still crash when removing AC power and on start up.

I have cross-check and I didn't do any typo.

[Miroslav (dzundam-deactivatedaccount)]

@szb

It would be helpfull if you attached some logs.

[ceg (ceg)]

@szb
For me it first kept crashing on battery when network-manager connected to wlan, but now, a couple reboots/updates? later the workaround works.

[dsn0wman (josgray)]

This effected me in 10.10, and it seems like I have the same symptoms in 11.04. Hopefully the same work around does the same trick.

--Dell Studio XPS 1645

[Vinay (vinay-wagh)]

I am still on 10.10 and the problem is still continuing. I have tried both the (main) solutions.

By the way, I found one interesting thing about this "freezing". The system doesnt get frozen completely, it is just the display and the inputs (keyboard-mouse) are frozen. I can still work over the network, if I have some music playing, it continues to play (even youtube is continued). More interestingly, my gmail status icon also remains the same (showing I am still available or busy or whatever)... Is there any way, I can unfreeze display & KB-mouse via ssh?

I am not sure whether this will help to solve the problem...

@Miraslov,
Where does one check the logs after emergency sync (ALT+PRINT+S). I just get two lines in the /var/log/messages:
SysRq : Emergency Sync
Emergency Sync complete

-- VInay

[Miroslav (dzundam-deactivatedaccount)]

It seems the bug is gone (at least in my case),
I can't crash the machine.

I wanted to check what's the bug status, so I
removed the kernel parameter pcie_aspm=off
from /etc/default/grub,
did sudo update-grub,
rebooted,
checked dmesg log that pcie_aspm=off is really
not activated, then pulled off the power cord
and waited. Nothing happened.

I rebooted the machine few times, plugged and
removed the power cord and nothing bad has happened.

I type this post on laptop running on battery.

I will watch the machine for some time.

[Miroslav (dzundam-deactivatedaccount)]

@VInay
do you mean your log is completely empty
except 2 emergency sync messages??
My log is full of messages mainly from
kernel boot.

[ceg (ceg)]

@Vinay: Yours may be another bug, at least mine crashed hard when enabling wlan on battery. If your kernel is still running, ALT-PRINT-K will kill your processes, but may restore your console input for you.

@Miroslav: Are you refering to 11.04?
In 10.10, mine used to work fine as long as wlan isn't enabled (laptop button).

[Miroslav (dzundam-deactivatedaccount)]

@ceg
Running 10.10

[bealer (robertbeal)]

This is still happening in 11.04 on my Dell Studio 15. Looks like I'll be reverting back to 10.04. Am amazed such a critical bug hasn't been fixed, and may not be fixed until 11.10.

[David A. Cuadrado (krawek)]

installing "laptop-mode-tools" (sudo apt-get install laptop-mode-tools) fixed the problem here. I'd try that before downgrading.

[Thomas Lenarz (tommesml)]

I tried Ubuntu 11.04 on my ASUS X51 Laptop.
Problem persists.

Then, I installed laptop-mode-tools additionally.
Problem still persists.

[Rob van der Linde (robvdl)]

I tried Ubuntu 11.04 amd64 on my Vostro 3700 and the problem still persists, also you cannot uninstall pm-utils to put on pm-utils 1.3, because that will also remove gdm and many other pakages. I have not found a workaround yet, installing laptop-mode-tools does not fix the problem, and neither does adding pcie_aspm=off to grub and running update-grub.

I am dissapointed to see this bug carry over to another version of Ubuntu, I am really hoping this bug will be fixed with Ubuntu 11.10, as it affects so many people with laptops purchased in the last year or so.

[aspera (aspera10)]

@Rob van der Linde

Uninstall pm-utils and makea notice about all the packages which will remove and reinstall it again (without pm-utils 1.4). Then you should be able to install pm-utils 1.3. For me it works on 11.04 with dell vostro 3700. ...but I can't give you a warranty.

[Tao Huang (greatht)]

System froze again after a fresh installation of Natty.

[Miroslav (dzundam-deactivatedaccount)]

I installed 11.04/64 on another drive to give it a try
and it freezes again.

Interesting, 10.10/64 doesn't crash anymore on my
system (see my post #124) but 11.04 does...

[Jorge Alban (jorgealband)]

Writing this on a Vostro 3700 Core i7 with Nvidia GT216 [GeForce GT 330M] and Broadcom BCM 43224 on battery alone. Before editing "pcie_aspm=off" into the grub, the machine froze completely within 15 seconds of disconnecting the power supply.

This behaviour started after installing Ubuntu 11.04 and continued with Linux Mint Debian XFCE [2.6.32-5-686] until applying the above mentioned fix (from comment #37)... so It might well be an upstream kernel bug.

It didnt happen with Linux Mint 9 LXDE - Ubuntu 10.04 based - but I upgraded to Ubuntu 11.04 in an attempt to acquire CPU throttling as my Vostro 3700 recently required servicing from overheating and turning itself off after 15 min of Handbrake video encoding. Tech service told me thermal compound was all over the place, so comment #114 by Mateo about Core i7 Linux laptops not being able to handle the heat from makes a lot of sense to me now ! -

Anyway thanks to this thread I can now use my laptop unplugged, the way it is supposed to work, and have CPU throtlling. If you need any other info or output just let me know, Ill monitor this thread for the following week.

[Jorge Alban (jorgealband)]

UPDATE: Both Ubuntu Natty Narwhal and Linux Mint 11 (Natty Based) eventually froze my Vostro 3700 again, even with "pcie_aspm=off" added to grub. It does so even while plugged to AC and on a relatively light CPU load...

Linux Mint Debian XFCE with kernel 2.6.32-5-686 and the above fix, doesnt freeze at all. It also runs my Core i7 much cooler (and comes with MLT 7.2 so Kdenlive 0.8 can be installed from repos). Just transcoded a one hour video in Handbrake. It got hot, but it didnt shut the laptop off.

[Thomas Lenarz (tommesml)]

UPDATE for ASUS X51:

I have tried the Fedora 15 Live Image. The Freeze occurs as well in exactly the same manner.

Therefore, the follwing distributions are affectet (for my laptop):

Debian (Squeeze)
Ubuntu (since 10.04)
Mandriva
Fedora (15)

The problem for me came with the upgrade to Ubuntu 10.04. from the previous version.

I suppose it must be a basic problem because it is shared by some very different distributions.

[Brod Justice (brod-l)]

FWIW: I followed the above, specifically:

1) Edit /etc/default/grub and change:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"

2) sudo update-grub

My Dell Vostro 1015 with 64-bit Ubuntu 11.04 no longer hangs when the AC power is removed. Thanks!

[Chandra Gupt Karn (chandraguptkarn)]

add another dell studio 15 to the list of victims of this bug

[Piotr Kujawski (elektrownia)]

Hi.

Dell Vostro 3700.

Problem "solved" by downgrading pm-utils to 1.3.0 on 11.04. With pm-utils 1.4.x the laptop freezes or reboots randomly after few minutes. AC powered a little less, battery powered more often. Other solutions described here not helped.

[Carl P (cparkinson)]

Hi,

I have been having problems with my Dell Studio 15 freezing intermittently when on battery for months. I have read many, many posts on this topic and tried many different tweaks to no avail. Reverting to an earlier version of pm_utils worked, but I lost the ability to put my laptop on standby, so that was no good. I decided it was time for me to do some analysis and try a few tweaks of my own. Well, it looks like I have come up with a successful work around that should work for any type of wireless card.

I run Mint 10 and have the latest version of pm-utils installed - 1.4.1. tailing /var/log/pm-powersave.log reveals that /usr/lib/pm-utils/power.d/wireless is called to put the wireless card into powersave mode when the power cord is removed. I found the specific section of code that makes that change is at the end of the script:

case $1 in
    true) wireless_powersave on;;
    false) wireless_powersave off ;;
    *) exit $NA ;;
esac

I simply changed it to:

case $1 in
    true) wireless_powersave off;;
    false) wireless_powersave off ;;
    *) exit $NA ;;
esac

This results in the card never being put into powersave mode and has stopped the freezing. This change does not appear to affect the power consumption either. So, all is well and I have said goodbye a very frustrating problem. I hope it works for you too.

FYI, my wireless card is a Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

[Thomas Lenarz (tommesml)]

I tried workaround from #141 on ASUS X51:

I am very sorry it does not solve the problem. Though, I think to observe that it takes a few seconds longer before it freezes.

ASUS X51 seems to be very resistent to all suggestions ;-).

The problem also persists on my Dell Vostro 3700 with Ubuntu 11.10. Everytime I forget to plug in the power cord, I get reminded of this issue. I'm hoping that this will be fixed very soon, I have been experiencing this bug for more than a year now. I like the Ubuntu OS but I'm missing stability.

The system freezes after an unspecified time running on battery. When reconnected to AC power, it will come back to life again most of the times.

I tried the workarounds described in comment #50 and #76, but they didn't work for me.

aspera, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.

sorry I am late, but I've got a lot to do in the last few weeks. I'm running Ubuntu 12.04 and it is daily updated ( it is really a great releas!!!). But the bug still happens! After a few seconds Ubuntu crash.
 I did run the command "apport-collect -p linux 656745" But I did it with power ac-adapter.
I hope Icould help. But I don't know where I have to refer the issue and do the tags. Maybe you can do it for me. Sorry I am not able to do that. I am a normal user and english is not my native language.

Thank You

[Jost Menke (jmenke)]

aspera, could you please try the 3.4 mainline kernel (see #161) and report if it still crashes?

[aspera (aspera10)]

@ Jost Menke,

Sorry I'm not able to try it, cause I haven't the knowledge to do that . Mabe you can explane it in short words? I'm using this laptop as a productivity system and I know nothing about the risk to try the mainline kernel. I like to help, but I have to do my work, too. But I will see what I can do...

[Thomas Lenarz (tommesml)]

> Please test mainline kernel 3.4 RC2 and report back:
>

I tried the mainline kernel on ASUS X51:

The effects are:

-System does not freeze anymore when unplugging AC-Adaptor and running from Battery. Power-Management (Indicators) appears to work properly.

-Two Messages appearing on startup: The first one ata1: softreset failed.... Sorry, they disappear too fast to take full notes.
-System does NOT start up with AC disconnected. It freezes on startup like before. You have to start it up on AC and then unplug AC for being able to run it on battery.

Please don't hesitate to contact me if I can test anything else.

[Jost Menke (jmenke)]

@Thomas Lenarz: Hmm.. So there seems to be some improvement with the 3.4 kernel, but no final fix. In the meantime, RC4 is out, maybe you want to give it a try:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc4-precise/

PS: Did you check if your BIOS is up to date? As others already mentioned, especially the ACPI stuff tends to be broken.

[Thomas Lenarz (tommesml)]

@Jost Menke: Thanks a lot for your reply. I tried the RC4 of the kernel. No change:
It works OK on battery when I pull the plug after start up. Booting up on battery does not work.
The freeze occured just after the sound was played on presentation of the login panel.
A short time after freezing, the screen went blank and I had to switch of manually.

My BIOS is not the latest one. There have been updates by ASUS. However, there was no documentation that any of the updates would fix ACPI problems. Anyway, I haven't got Windows for use of my laptop since it shipped with FreeDos as operating system. ASUS only provide their BIOS-updates in the form of Windows installers which unfortunately leaves me unable to install a BIOS upgrade.

[penalvch (penalvch)]

Thomas Lenarz, please execute the following via the Terminal and feel free to subscribe me to it:
ubuntu-bug linux

Thanks!

[Thomas Lenarz (tommesml)]

@Christopher: Done. It is Bug #995223.

However, I had to boot again with the last Ubuntu kernel. ubuntu-bug did not allow me to file the bug with active mainline kernel. I hope this makes no difference for the information you need.

Thanks a lot!

[Jost Menke (jmenke)]

Thomas Lenarz: I really strongly advise you to update your BIOS first. Manufacturers tend to fix things without neccessarily mentioning it in the changelog. For example, on my HP nx7400, Speedstep didn't work in Linux until I updated the BIOS to the latest version. The documentation said nothing about it.

If Asus really offers Windows only updates for a product that shipped with DOS, I'd nag them to supply an alternative. Which exact model of the X51 do you have? For the X51R, there is a DOS update procedure:

I'm not a very experienced linux user, but I'm willing to help to solve this problem. If anybody could give me an instruction, how to create a bug report? But I can't install 12.10 Beta 2, because I'm working still with Ubuntu 10.04.
I installed the actual beta version on an usb device. Answer, please.

aspera, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.7-rc8

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

I tested the latest mainline kernel and can confirm that, the bug still exists on the folloswing mainline kernel:
Linux 3.8.0-999-generic #201212310405

I have used this kernel also after disabling proprietary Wireless lan driver. But that didn't help avoid the crash either.

Nevertheless, I found a workaround for this issue:
Setting the following boot option solves the crash problem:
pcie_aspm=off

The above boot option can be easily set by editing /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"
And then running "update grub" command.

Thanks.
