CPU0:; EIP is at arch_local_irq_enable+0x5/0xb

[Emmanuel Castro]

When the Compaq nc6400 is on battery, it freeze randomly (mean time 15 minutes).
Everything including the move get frozen, however it SysRq key works.

Please find attached some info taken on the netconsole: the cpu-backtrace, and some complaints from processes.

I can see that the both CPU are blocked in acpi_idle_enter_bm+0x227/0x25e

With which version of the kernel do you want me to retry the catch the bug.

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). 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 by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

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'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Thanks in advance.

[Emmanuel Castro (emmanuel-castro)]

I've tested with 3.2.0rc4. It still freezes, but not the same way. It freezes "more slowly" (reproduced 3 times).
At first, I can move the mouse, but the clicks and the keystrokes fail.
Some background applications still operate (I could see a blinking cursor on a gnome-terminal), but there is no way to interact with them.

However I can switch to the text mode consoles (Alt+Ctrl+F1 or F2...). Sometimes I can type in, but I does not last long (just the time to type my login, no chance to type the password - If I ever get the password prompt).

At this point, I could use SysRq. You find 3 files attached.
I noticed that both Cpu stacks are at: cpuidle_idle_call+0xab/0x1d0

Before that, I noticed that (may its normal):
When I put the laptop on battery
[ 116.498481] Monitor-Mwait will be used to enter C-3 state
[ 116.861874] EXT4-fs (sda3): re-mounted. Opts: errors=remount-ro,commit=600
[ 116.866674] EXT4-fs (sda6): re-mounted. Opts: commit=600

I've let the laptop alone for a few seconds and I got that.
[ 151.580090] CE: hpet increased min_delta_ns to 20113 nsec

[Emmanuel Castro (emmanuel-castro)]

Tell me if it is usefull

[Nick Allen (nick-tallguy)]

Also affects me - I have a 1.8ghz model & a 2ghz model, each with 3gb ram. Has taken me some time to realise the freezes were on battery power. I'm still not entirely sure, but will keep checking & will update this if I find anything different. The report so far seems more comprehensive than I am currently capable of, but I'm willing to learn & try anything suggested

[Nick Allen (nick-tallguy)]

Forgot to add, have also experienced this in Lubuntu, and ubuntu running Gnome desktop

[Jost Menke (jmenke)]

I am (probably) experiencing the same problem on an HP Compaq nx7400 running Xubuntu 12.04 daily (3.2.0-18-generic-pae #28-Ubuntu SMP Fri Mar 2 22:11:12 UTC 2012 i686 i686 i386 GNU/Linux).

The system will become unresponsive after an unspecified time running on battery.

When reconnected to AC power, it will come back to life again.

[Jost Menke (jmenke)]

I tried the mainline kernel

3.3.0-030300rc7-generic-pae #201203101735 SMP Sat Mar 10 22:52:51 UTC 2012 i686 i686 i386 GNU/Linux

and it seems to fix the issue for me. Running on battery for several hours now without freezes. Maybe somebody else with this problem wants to try: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.3-rc7-precise/

[Ian Hodgson (ian-hodgson-home)]

Sorry for an utterly 'newbie' type question, but can someone point me to a guide that explains step-by-step how I can take the files at the end of the URL and apply the patch to my Ubuntu machine. Thank you.

[Emmanuel Castro (emmanuel-castro)]

...depending on whether you have a 32bit or 64bit installation.
Then, install the deb file. You might be able to double-click on it, however the standard procedure is to use the command line:

sudo dpkg -i linux-image-(...).deb

It installs automatically and registers in grub.

You just have to reboot and select the new kernel at boot time.

Good luck

For the newbies: You're welcome, you can fruitfully learn apt-get (install | remove) and dpkg commands.

[Jason St. JohnComp2 (jason-st-john)]

Emmanuel, grazi mille.

For about four years I have had this HP nc6400 running Gentoo and more
recently, Ubuntu. In both, it exhbited this bug, and froze all its
onboard inputs after an apparently random interval when running on
battery. The kernel version you found and shared has freed it from
being chained always to the power converter. It's just like a real
laptop, now!

Many, many thanks,

[Jost Menke (jmenke)]

Emmanuel, does 3.3.0-030300rc7 fix the problem for you aswell?

[Jason St. JohnComp2 (jason-st-john)]

[hp nc-6400, kernel 3.3.0-030300rc7-generic ]

Unfortunately, with another day or so of experience, I have to report
that this does not fix my freezing-inputs-on-battery-power problem,
after all. Three times now it has returned, just the same as ever.

Interestingly, there *has* been an improvement with the kernel change;
the suspend-on-close, which never really worked under Ubuntu (although
I eventually got it to work with Gentoo, once), now works just fine.
At least something is better about this kernel on this system!

Regards,
-jmsj

[Ian Hodgson (ian-hodgson-home)]

Sorry to report that my nc6400 locked up about 2 minutes after boot on battery with the patch installed.

[Jost Menke (jmenke)]

After some more testing, unfortunately the problem still occurs on my device aswell, even with 3.3-rc7. Sorry for raising up hopes here.

[Jost Menke (jmenke)]

Please test mainline kernel 3.4 RC2 and report back:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc2-precise/

Not 100% sure if this fixes the problem for me, I only tested a couple of hours now (without freezes). But it definitely fixes some issues I had with my builtin Intel 3945ABG wifi.

[Ian Hodgson (ian-hodgson-home)]

Up and running off PSU for much longer than ever before. I would guess that the bug is fixed with this patch; I'll report if I turn out to be wrong. Thanks to those who put this togther, I now have a laptop.

[Jost Menke (jmenke)]

aspera: please download http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc3-precise/linux-image-3.4.0-030400rc3-generic-pae_3.4.0-030400rc3.201204152235_i386.deb
and install it (simply double click on the file and follow the instructions). Afterwards, reboot and check if the problem persists.
To revert to the old kernel, simply run synaptic and uninstall linux-image-3.4.0.

[Jason St. JohnComp2 (jason-st-john)]

What is aspera? The Latin for "hope." It's some high-speed file
transfer software. But I'm stumped to see that word here. Jost Menke,
what do you mean?

Now on my second day after installing the kernel whose .deb you linked
to (HP Compaq nc6400, Ubuntu 10.4), and so far the old symptoms have
only shown up once. (Kernel freeze, perhaps, because the keyboard,
mousepad, and all onboard inputs cease to have any effect, and only
powering down is possible, yet the screen doesn't freeze.)

The one freeze incident coincided with having try to re-connect to
some Boingo Hotspot which was being unusually difficult. The problem
has long seemed tied to high room temperatures, and the use of
wireless. Could be that these simply give the kernel more to do,
making some collision more likely?

Anyway, this fix is testing well so far. Thanks, Jost!

Jost Menke, if your having a problem please execute the following via the Terminal and feel free to subscribe me to it:
ubuntu-bug linux

Thanks!

[Jost Menke (jmenke)]

@Jason St. JohnComp: I copied a comment from bug #656745 where I replied to a person named "aspera", sorry for the confusion. Bug #656745 seems to be sort of a duplicate to this one. Anyway, thanks for your feedback. So kernel 3.4 seems to be an improvent for you, 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: Just to make this clear: I am not involved in any patches or kernel development, I only had the idea to try out the mainline 3.4 kernel.

@Christopher M. Penalver:
Kernel 3.4 fixes the problem on my HP nx7400, after several days of testing I can say that I am sure about this, no more freezes in the meantime. ATM I am running 3.4 RC4 on Ubuntu 12.04. Too bad 3.4 won't make it into the official release of 12.04. So the question is, is there a way to find out what causes the freezes and backport the stuff needed to kernel 3.2?

[Jason St. JohnComp2 (jason-st-john)]

No problem about the aspera confusion.

I can now confirm that installing
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc3-precise/linux-image-3.4.0-030400rc3-generic-pae_3.4.0-030400rc3.201204152235_i386.deb
has completely addressed the original issue. It is a final fix. My hp
nc6400 now operates correctly (no kernel freeze) while on battery
power. This is the first and (so far) only fix I have seen, after
several years of searching for a solution!

I may try 3.4-rc4 at a later point. I'm happy to have a fully portable
laptop for now.

Many thanks for the idea,
-jmsj

Jason St. JohnComp2, if your having a problem in Ubuntu please execute the following via the Terminal and feel free to subscribe me to it:
ubuntu-bug linux

Thanks!

[Emmanuel Castro (emmanuel-castro)]

Sadly, I tried both rc3 and rc4 with and without Wifi, and my Hp NC6400 still freezes. I guess there is some non-compliant electrical behaviour in it.

I also guess that the kernel has some smart behaviour when on battery, and that this behaviour is too smart for my laptop. How can one disable it without disabling all the ACPI subsystem?

[penalvch (penalvch)]

Emmanuel Castro, thank you for testing the mainline. Could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc5-precise/ ?

[Zoltan Kiss (zkiss)]

I'm testing with v3.4-rc6-precise currently.
On battery, using built-in WiFi, it is still freezing randomly.
I would say that it freezes rather when I'm browsing the web.

[Emmanuel Castro (emmanuel-castro)]

I've tested with v3.4-rc5-precise with Wifi and without Wifi.
In the both case, it freezes. When Wifi is on, it freezes in 15 minutes. Without Wifi, it is longer: 1hour or more.

[penalvch (penalvch)]

Emmanuel Castro, could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc6-precise/ ?

[Emmanuel Castro (emmanuel-castro)]

I tried rc6 kernel off-battery twice today.
- without Wifi, I could use my laptop without problem for 1 hour without any problem. I had to stop the session before the battery exhausts for business reason. I'll retry longer latter.
- without Wifi, it froze after 20 minutes. I first noticed that the machine started slowing down. The CPU was not used a lot. I turned to console using Alt-Shift-F1 and tried to log in. I succeed, but it was damn slow before I could get the prompt. I opened an other console (F2), it was the same joke.
It seemed that running processes where running correctly, but starting new processes was very slow.
When running Top in console, there were no strange process behaviour.

Then I got a message from the kernel on the console. Please find attached what I've found in my kern.log.
30 second later, I had to REISUB.

[penalvch (penalvch)]

Emmanuel Castro, could you please report the results following https://help.ubuntu.com/community/DebuggingIRQProblems ? Feel free to skip the DebuggingSystemCrash part for now.

[Emmanuel Castro (emmanuel-castro)]

I'll start do it (IRQ...) this evening.

Beside, I noticed that since at least RC5, I get the following error messages on the console that is behind X11.

May 23 14:17:38 smeagol kernel: [ 2159.336747] ata5: ACPI set timing mode failed (status=0x300b)
May 23 14:17:38 smeagol kernel: [ 2160.360122] tpm_tis 00:04: A TPM error (7) occurred attempting to read a pcr value

It occurs at each boot, and each time when I suspend and wake-up the machine.

This morning, I encountered again the same problem as in post #32, however without Wifi (note that I misstyped in #32, the second bullet is "with Wifi"). I tried the sync command on the console, and it took at least 20 seconds. Then I pressed the hardware suspend key and the machine freezed with the kernel telling :
[<time and date>] BUG: soft lockup - CPU#0 stuck for 22s! [power.sh - 3940]
and some other lines that I have to extract from my phone-camera.

[Emmanuel Castro (emmanuel-castro)]

I've tested the procedure in https://help.ubuntu.com/community/DebuggingIRQProblems.
– noapic → freezed
– pci=routeirq → freezed
– pci=noacpi → freezed
– acpi=off → test in progress, but in this mode, the advanced capabilities of my video card are disabled, so it switches to Unity2D. I has not frozen... yet.

I'll try again the test using Unity 2D if you think it is relevant.

[SGD (sgd)]

I am also experiencing the same problem on the NC6400 running Ubuntu 12.04. I believe that I have found a duplicate bug in launchpad, see Bug #998379.

Is there any possible/planned fix for this issue?

[Nick Allen (nick-tallguy)]

Hi, problem still exists - does not appear to be linked to cpu load as sometimes the freeze occurs when there is very little activity.

[Nick Allen (nick-tallguy)]

Still exisiting problem. Yesterday I used the laptop for over 3 hours on battery, doing various tasks including using transmission & firefox, and laptop did not freeze at all.
Today laptop froze within 2 minutes of logging in. Had got as far as loading transmission, and Firefox & was just changing to a different website when laptop froze - on this occassion no mouse either.
On some occassions in the past the laptop has frozen - windows not responding, although it is possible to move the mouse around the screen - does not respond to mouse clicks though, or normal shortcuts such as alt+f4.
Always reboots using REISUB, although screen remains frozen until the final B is reached & reboot starts.

[penalvch (penalvch)]

[Brice (brice-wernet)]

I have the same problem with a HP NC6400.

X is freezes when on battery, usually when I'm browsing the web. I still can move the mouse. It's strange, because if I clicki on a menu, nothing happens UNTIL I press the power button. I can right click and then press the power button and the context menu shows.
Doing Alt-F2 I land on the console, I can type my login and password but it never log me in.

I did not upgrade from Ubuntu 10.10 until last month because I had a similar bug in ubuntu 11.10, but it was immediate during boot sequence.

[penalvch (penalvch)]

Brice, please see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/898852/comments/39 .

[penalvch (penalvch)]

Emmanuel Castro, thank you for providing the debugging information. Regarding your comments https://bugs.launchpad.net/ubuntu/+source/linux/+bug/898852/comments/35 :
>"– acpi=off → test in progress, but in this mode, the advanced capabilities of my video card are disabled, so it switches to Unity2D. I has not frozen... yet."

So, you could not get the computer to freeze on or off battery using this kernel parameter?

As well, as per http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=ca&prodNameId=1847704&prodTypeId=321957&prodSeriesId=1847703&swLang=8&taskId=135&swEnvOID=1093#120 your BIOS is outdated. Could you please upgrade to the newest one (F.0B) and comment if this problem is still reproducible?

Also, could you please test http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.2-quantal/ ?

[Emmanuel Castro (emmanuel-castro)]

I am sorry, but I can't proceed any test anymore because I don't have this
laptop anymore as my company provided me with a new (more powerful) one.

Actually, the few tests that I could perform on Unity2D did not hang.
However, the screen resolution was too poor for using it many hours.

Your hypothesis about the outdated kernel is interesting. I hope other
people will be able to test it.
