x201 intermittent crash on resume from suspend, with caps lock flashing

[Martin Pool]

This looks like a recent oneiric regression, perhaps in -8:

On my x201 thinkpad, about one time in four, the machine reboots when trying to come back from suspend.

I think it would suspend once, work, suspend again, crash, repeat. But it seems to be stable in 3.0.0-9.

[Martin Pool (mbp)]

This is consistently happening on the second suspend after rebooting in current oneiric.

[Brad Figg (brad-figg)]

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help.

[Martin Pool (mbp)]

i'm delighted to say this seems to be fixed in 3.0.0-11.18

[Martin Pool (mbp)]

Sadly, no: it's intermittent, but it is still happening in current oneiric 3.0.0-11 #18.

[Julian Edwards (julian-edwards)]

Hi - this is happening for me also with the current oneiric kernel (3.0.0-12-generic). It happens about 70% of the time I resume from suspend.

I have a T410 though:
model name : Intel(R) Core(TM) i5 CPU M 540 @ 2.53GHz

If you want this bot to quit automatically requesting kernel tests, add a tag named: kernel-bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

[Julian Edwards (julian-edwards)]

Happens on 3.0.0-12.20

[Martin Pool (mbp)]

Still happening in 3.0.0-13.22, with the variation that it now sometimes just reboots with no caps lock flashing.

Do you have any advice other than trying to bisect back through previous versions?

[Joseph Salisbury (jsalisbury)]

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 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 others). 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 3.1-rc9 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.1-rc9'.

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

Thanks in advance.

[Martin Pool (mbp)]

The hang with caps lock flashing happens with 3.2.0-030200rc1. In addition
the ipw2200 wifi does not seem to work in that version.

I don't know if this is related, but I noticed that sometimes this machine reports only one cpu in /proc/cpuinfo, and it has these dmesg entries:

This is still happening on precise from last week, with

Linux joy 3.2.0-7-generic #13-Ubuntu SMP Sat Dec 24 18:06:57 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

still has this problem, at least to the extent that after the first resume, all but one cpu core is gone.

[Martin Pool (mbp)]

ok, thanks to colin and apw, we localized this to actually being due to powernap taking the cpus offline. with powernap-common purged, the problem is fixed.

[Julian Edwards (julian-edwards)]

\o/

Thank you thank you thank you.

[Soenke (s0enke)]

I had the same problem (11.11), but powernap NOT installed. Installing cpufrequtils fixed the problem for me. Now all CPUs are restarted properly on resume. I found this solution here: https://answers.launchpad.net/ubuntu/+source/acpi/+question/155520
