CPUs get stuck in Turbo mode after a suspend/resume cycle on a ThinkPad X220

[Marius Gedminas]

Often, but not always, after I suspend and resume my ThinkPad X220, I notice that the laptop becomes hot, the fan is constantly spinning, and powertop shows all four CPUs stuck at 2.5 GHz.

Suspending and resuming again fixes the issue.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Installed. Rebooted. uname -a shows

  Linux platonas 3.12.0-031200rc1-generic #201309161735 SMP Mon Sep 16 21:38:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

At first I thought the issue showed up right after boot, but now I'm no longer sure. Could be just the ondemand governor ramping up the frequency because of all that CPU activity during boot/login.

In normal circumstances the laptop's idle temperature is about +48–49°C. When this bug happens, temperature rises steadily until it reaches about +72°C.

At the moment, with the 3.12 kernel, the temperature is oscillating between +50°C and +54
°C.

I was unable to reproduce after two suspend/resume cycles with kernel 3.12. But then with raring's normal kernel this bug used to occur maybe twice a month. I'll continue using 3.12 and see if this happens again.

Incidentally, this linux-thinkpad@ thread may be about the same issue: http://mail.matrix.de/pipermail/linux-thinkpad/2013-July/051462.html
I tried to talk about my issue on the list, but didn't receive any answers: http://mail.matrix.de/pipermail/linux-thinkpad/2013-July/051476.html
