Suspend problem with Maverick on ThinkPad W500

[Thomas Dreibholz]

Binary package hint: pm-utils

Suspend with Maverick/64-bit on ThinkPad W500 is very unreliable. In about 1 of 3 cases, the system hangs with dark screen and suspend LED blinking. I have used pm_trace to track down the problem:
[ 0.963116] hash matches /build/buildd/linux-2.6.35/drivers/base/power/main.c:544

Description: Ubuntu maverick (development branch)
Release: 10.10

[Thomas Dreibholz (dreibh)]

I have captured another dmesg output of a failed suspend:
[ 1.002034] Magic number: 0:248:190
[ 1.002091] acpi device:1c: hash matches

The full dmesg output is attached.

[mycl (415fox)]

I have the same symptoms on a Lenovo X200 with Maverick Beta.

Except, when I went through the suspend debug process I didn't get a device hash matches line. My Magic number was:

[ 0.681422] Magic number: 0:898:740
[ 0.681465] hash matches /build/buildd/linux-2.6.35/drivers/base/power/main.c:586

Thomas, could you please post the results of:
lspci -vvv

so we can see which device matches your hash?

[mycl (415fox)]

Oops. I see you did post your lspci. It looks like the kernel modules shpchp and pciehp. I tried adding the lines:

blacklist shpchp
blacklist pciehp

to /etc/modprobe.d/blacklist.conf

I've gone through a couple of suspend/resume cycles successfully. But, since this is an intermittent issue, I will have to continue to use it for a day or so to see if this really fixes it.

[mycl (415fox)]

Fail. The above does not prevent the problem.

[Thomas Dreibholz (dreibh)]

I have tried "blacklist btusb", since I noticed some error messages on btusb in /var/log/syslog. But no change, the suspend problem is still there.

A "lspci -vvv" output is now attached. May be the more verbose output can help somebody identifying the problem.

[mycl (415fox)]

This might be the solution:

At some point, a few Ubuntu iterations back I put the following lines in my /etc/modules file:

thinkpad_ec force_io=1
tp_smapi

This was recommended by the thinkwiki x200 page to try to get the accelerometer-based active hard-drive protection working, as well as to set charge-discharge limits for longer battery life.

I've since upgraded to an Intel SSD (which is awesome!) and I guess I'm willing to throw battery life under the bus. After removing these two lines I've been able to suspend successfully for two days.

[mycl (415fox)]

Also, if you think that Bluetooth is causing problems you can disable it in BIOS setup at boot.

[mycl (415fox)]

Son of a bitch is back. Although it seems a lot more infrequent. It just happened for the first time in a few days.

[Mark Cocker (mark-earth)]

Re comment 8, the Thinkpad W500 BIOS (V3.15/3.17) configuration doesn't have an option to disable Bluetooth.

[mycl (415fox)]

Since I can't trap this bug using the normal CMOS-clock-based method, and since so far it only seems to affect thinkpads, I'm going on a lark and blacklisting thinkpad_acpi. So far I'm not seeing any reduction in functionality. Suspend/resume has worked a few times successfully, but so it has in the past with other experiments. All LEDs, wifi, special keys, battery, powertop and sound are working correctly -- so who knows what functionality that module is even providing.

[mycl (415fox)]

One thing I am definitely seeing is a faster suspend/resume process. In the past, even when successful, it has taken about five seconds to suspend. Now, it's more like one.

[mycl (415fox)]

There. I just did 10 successful suspend/resumes in a row. If this is good for a couple of days, I'll try to figure out who owns thinkpad_acpi and send them the bug.

[mycl (415fox)]

No help. Still the occasional freeze up. I tried the kernel suspend debug thing again, and here is the message:

[ 0.701281] registered taskstats version 1
[ 0.701579] Magic number: 0:898:740
[ 0.701621] hash matches /build/buildd/linux-2.6.35/drivers/base/power/main.c:586

So, still no indication of a device to blame.

[Dukai Gábor (gdukai)]

I have a similar problem on a T500. The difference is that I rarely manage to make it suspend at all.

For sure it's not the bluetooth because I tried with bluetooth unloaded. I tried to unload thinkpad_acpi, hdaps, tp_smapi and thinkpad_ec. Only one time with all of them unloaded I managed to make it suspend. Next time it didn't work.

I didn't have suspend problems before maverick.

[Thomas Dreibholz (dreibh)]

I have tried the following blacklist entries:
blacklist btusb
blacklist thinkpad_acpi

Unfortunately, this has not been successful. The suspend problem still exists as before.

[Akagi (akagi010)]

Hi,

in bug report #659668 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/659668/comments/23) a workaround is given. This workaround stopped to work for me after todays update of my Ubuntu 10.10 installation.

Obviously there are at least two mechanism to suspend a T500 laptop: One for the session plugin of the top panel and another one if one uses the On/Off-Button of the laptop. The said workaround only worked for the session plugin.

Best regards!

[timobaumann (timobaumann)]

"me too" on a T500; I also have an SSD so may this be an indicator?

[Ralph Meijer (ralphmeijer)]

timobaumann: My T500 does not have an SSD, but does experience the reported issue.

[Thomas Dreibholz (dreibh)]

As a work-around, I have now self-compiled a 2.6.36-rc8 kernel from the kernel.org git repository, just using the configuration from /boot/config-2.6.35-22-generic. Suspend/resume works fine with the new 2.6.36 kernel and I have not seen any other problems yet.

Note: I am using the Intel graphics chipset of my W500, having the ATI one deactivated in the BIOS settings. Therefore, using the 2.6.36-rc8 kernel as work-around may not work for people using the ATI chipset (and closed-source fglrx drivers) instead.

[Greg Tabor (gat92)]

Referencing back to my comments on bug 659668, now marked as duplicate of this one...

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/659668/comments/23

I believe this hack only works for lid close as reported by akagi above. The recent kernel updates did not fix the problem, but replacing my hack restored the workaround after the updates.

My experience has been that the bug only affects intel graphics on my W500. When I switch the BIOS config to the ATI graphics chip (and the open source ati driver) suspend works fine for me with Maverick and without my pm-suspend hack. Another poster to ubuntuforums (http://ubuntuforums.org/showthread.php?p=10009357#post10009357) reports that suspend works fine for him with a clean Maverick install using the ATI chip and the fglrx driver.

Glad to hear it's fixed in 2.6.38. Hopefully we can get the relevant fix, whatever it is, pushed out in a released Maverick kernel.

[Akagi (akagi010)]

I installed the mainline kernel v2.6.36-rc8-maverick and it fixes the problem also (at least for me). Now suspend works without Gregs workaround.

There might be still an issue if a docking station is involved: When I detach the notebook from the docking station (and go to battery) and suspend it fails. But this might be another issue.

[Dukai Gábor (gdukai)]

I have the same issue with a docking station and a T500.

[ReneS (mail-03146f06)]

Seems to be gone with 2.6.36 Maverick on my T500. Willl keep an eye on it.

[Michal Smid (michalsmid)]

I can confirm this bug on Toshiba U400. About one third of the suspendations just freezes the computer and the fan speed increases.

[bofphile (bofphile)]

Same issue on my T500 (model :2082-7SG). Suspend worked perfectly fine on previous versions of Ubuntu.

[gdi2k (gdi2k)]

In case it helps, I have the same on my ThinkPad X200 with Intel graphics, so it's not just the big ThinkPads.

[Kapil Thangavelu (hazmat)]

i can confirm the bug on a T400 with intel graphics as well. i get either blinking sleep light indefinitely (on lid close) with the cpu running hot, or on pressing suspend hot key, i'll sometimes get a reboot instead of a sleep.

[jhfhlkjlj (fdsuufijjejejejej-deactivatedaccount)]

I am on an Acer Aspire 5734Z and I had the exact symptoms described above.

My dmesg only showed:

[ 0.964933] Magic number: 0:898:740
[ 0.964935] hash matches /build/buildd/linux-2.6.35/drivers/base/power/main.c:586

I updated to the 2.6.36 kernel and the issue seems to be resolved.

[mycl (415fox)]

I have a work-around that seems to be working.

Create the file:

/etc/pm/sleep.d/20_chvt_mjf

And make it executable with:

chmod a+x /etc/pm/sleep.d/20_chvt_mjf

And put the following inside:

#!/bin/sh

case "$1" in
  suspend) chvt 1; ;;
  resume) chvt 7; ;;
esac

return 0

[mycl (415fox)]

The fact that this works tells me that this problems has something to do with the graphics driver, though I can't say what exactly. This is my graphics controller. Does yours match?

Although I get the suspend problem in Ubuntu Maverick (where the problem did not happen with Lucid), I get no problem with Debian Squeeze -- so until things are fixed in Maverick I am running Squeeze. Perhaps this triangle of version numbers of kernel and drivers can help discover what the problem is?

[gervin23 (gervin23)]

I just upgraded my Thinkpad T60 to 10.10 and experienced a similar problem (actually 2). First problem was the machine wouldn't suspend. The sleep light blinked but at the usual point of powering down it jumped back alive asking for login. I tracked it down to partport_pc failing to disable. I then tried unloading parport, parport_pc (and any other depending on partport) but got the unending blinking sleep light and had to pull the plug. Upon reboot I re-enabled parallel port in the BIOS which ended up fixing the problem.

[Michal Smid (michalsmid)]

On my Toshiba U400 I have the same (or similar) graphics card as mentioned above (Intel Mobile 4 Series Chipset Integrated Graphics Controller), so the problem may be related to it.

As a temporary workaround I use the command (as proposed somewhere)
acpitool -s
to suspend the computer, which works fine.

[Akagi (akagi010)]

After I used two of the workarounds (1. a script /usr/sbin/pm-suspend and 2. mainline kernel 2.6.36 with drm-next) for two weeks I come to the conclusion that both are not reliable. To be honest: They fail in 30-50 %.

In some cases the notebook (Lenovo T500) fails to suspend as usual, in other cases the notebook fails to resume. In this case the moon and battery LEDs are on, but nothing happens. Normally the "flash" and disk LEDs are also active shortly afterwards.

[Robert Entner (robertentner)]

For me using the kernel of Ubuntu 10.04 works perfectly fine and reliable. The same on my daughter's Laptop (Lenovo with Intel graphics).

Dell Latitude E6400 with Intel graphics.
Linux bdell 2.6.32-25-generic-pae #44-Ubuntu SMP Fri Sep 17 21:57:48 UTC 2010 i686 GNU/Linux

[Edward Parker (bontano)]

Same problem here on a T400, 64 bit Ubuntu desktop. Suspend worked fine until upgrade, now locks up and must be forced to reboot.

[gervin23 (gervin23)]

Scratch my comment (#33). The bios settings seemed to work a few times but now stays in sleep mode and requires power down. Greg Tabor's pm-suspend workaround is working so far (ATI with open source driver).

[Michael A. Phillips (maphilli14)]

I had all the symptoms above, flashing moon, power off as the only soltuion. My W500 was using 10.10 after upgrade form 10.4. I switched the BIOS from integrated to descrete (Intel to ATI) and haven't done anything else. Things are 100% so far. I'm up to 3day uptime now! Before, it was totally unusable, now, works but my battery suffers! :(

[mo (deez)]

The solution by mycl (comment #30) solved this for me on a Thinkpad X200 with a Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller. Constant success for over two weeks now.

[Mihai (udev)]

Using the 2.6.36 kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-maverick/linux-image-2.6.36-020636-generic_2.6.36-020636.201010210905_amd64.deb seems to have fixed it for me. (T400, Intel 4500MHD graphics)

[Michal Smid (michalsmid)]

The kernel update proposed by Mihai (#41) did not worked for me.

[gervin23 (gervin23)]

Scratch my comment #39. None of these workarounds are working consistently. This is extremely annoying.

[Alin Trăistaru (alindt)]

This problem seems to have dissapeared (at least for me on a T500) from 2.6.35-23 on with parport and tpm_tis modules blacklisted:

blacklist parport
blacklist parport_pc
blacklist ppdev
blacklist lp
blacklist tpm_tis

[Tomas Kliegr (klieto)]

Same issue on my T510i 4313-8AG with Intel HD Graphics on Ubuntu 10.10 with kernel 2.6.35-24-generic. Suspend and hibernate are both very unreliable (literally stopped working). It worked fine recently, it could be perhaps blamed to the recent kernel update.
The system freezes during suspend or hibernate, with the sleep indicator blinking indefinitely.

[ReneS (mail-03146f06)]

This problem occurred once so far with 2.6.37 on my T500. Interestingly not even the TFT was switched off. The login screen came back on, the system was frozen, and the moon flashing.

[Nils Fredrik Gjerull (nfg)]

I can confirm this bug on my Dell Latitude E5400, which also uses a Intel Mobile 4 Series chipset (rev 07).

I have installed the 32-bit version of Ubuntu Maverick running kernel 2.6.35-24-generic. The laptop has a 64-bit CPU.

None of the proposed workarouds work for me, except for to use "acpitool -s" which works fine to suspend.

The only problem was that it needed root privilegies, which was very annoying.
But it can be bypassed by adding line "%michal ALL=NOPASSWD: /usr/bin/acpitool"
using "sudo visudo"

I am using kernel 2.6.37 since more than two weeks now. Using this kernel version, suspend to RAM and hibernation work fine on my Thinkpad W500 running 64-bit Maverick.

In that case, let's close this bug. Please file a new bug if suspend still fails
for anybody using this model -- it's probably not the same bug.
