I can reproduce this every time the system is under load and it always results in a trace to intel_thermal. My system has 2 intel xeon 5670 processors. Reproducible: Always Steps to Reproduce: 1.Run a computer intensive process until the cpu fans increase their speed and the cpus reduce their speed -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Over the weekend, 3.3-final was released and I updated Kernel:HEAD to use it. Once it's updated at http://download.opensuse.org/repositories/Kernel:/HEAD/standard/ (version should be 3.3, not 3.3-rc7), can you try testing with kernel-vanilla again? If you have a digital camera, taking a photo of the oops and attaching it is more useful than a transcribed log. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It may, however, be a hardware fault. If I enable the watchdog timer in bios I will get a reboot after some time, but it isn't triggered in the same way as the kernel watchdog. I haven't figure out yet what causes the bios watchdog to reboot as unplanned reboots aren't healthy for filesystems. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=742088 https://bugzilla.novell.com/show_bug.cgi?id=742088#c22 --- Comment #22 from Federico Vecchiarelli 2012-07-03 23:48:33 UTC --- Rafael, Please see previous comments, this doesn't happen with earlier kernels. Citing it here: "I have the same issue. Which is resolved by going back to Kernel-3.1.10-1.9. I did tests switching between Kernel 3.1.10-1.9 and 3.3.4-22. The issue appears every time I switch to 3.3.4-22." I'm forced to stick to Kernel-3.1.10-1.9 as moving to a newer kernel makes my laptop crash with this problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have just started following this thread. Experienced similar symptoms on 11.4 with kernels > 3.4.0-15.1. Following a clean install of 12.1, all was well with kernel(s) 3.1.10-1.16-default. Ensuing updates, via repo /Kernel/HEAD, to kernels 3.5.<anything>, up to and including 3.5.0-4.1, manifest these exact symptoms, albeit only on ATI graphics. (Strangely, an install on Intel Arrandale graphics performs admirably!). I do not have an Nvidia-based platform to test). No "Bluetooth" hardware is involved, and these symptoms are manifest of the -vanilla versions of the 3.5+ kernels. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I went through kernel/v3.x/ChangeLog-3.5.1, but I couldn't find anything obvious. While the changelog is rather long, there are not much general or mce patches which could affect this. Of course I still might miss it. For now we expect things got fixed between 3.5.0 and 3.5.1, right? Strange..., hopefully things get magically fixed in 3.4.X stable kernels as well. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

has been running with and without loads for 7+ hours without issue Not that the issue is papered over because 3.5.1 has a "power save" fix or similar.

Are you sure you took -vanilla flavors for successful tests? It could be related to bug #756085. acpi-cpufreq driver was not loaded because of a module dependency. The fix only is in SUSE kernels (-desktop, -default, ...) where needed (latest 12.2 and master branch), but I have to re-submit mainline. While on such modern CPUs acpi-cpufreq shouldn't be that much of a difference, this (loading or not loading acpi-cpufreq driver) could be the reason for different thermal heat up behavior under load. If the thermal event condition happens there should be an MCE or TRM interrupt incremented in /proc/interrupts. You might want to double check whether this is true. Can someone say for sure whether the machine hangs immediately on the first thermal event or after some time (when quite a lot events may happen)? If this can still be reliably reproduced with latest kernel(s) in some way (put something in front of the fan slot until critical temp is reached if it's a laptop?), it would be great if blacklisting edac drivers as mentioned in comment #46 can be tested. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Ran for 12+ hours, pushing the proc AND temps to highs without failure. Test of 3.5.0 (-4, -8 and -10), -vanilla and -desktop, resulted in failure within <5 minutes, at first loading (Firefox w/Flash).

Found that interesting, as the failing 3.5.0 kernels (see above for versions and -flavors), would (almost) drain the battery while sitting on the CPU lockup and/or panic. (I noticed this after floundering my photographic talents getting screenshots). Further testing, with 3.5.2-1.1-vanilla AND 3.5.2-1.1-desktop (finally!) resulted in quite satisfactory results (NO lockups or panics). The proc load was assisted by a heretofore unseen CPU-load from "tracker" ! That being resolved (and suppressed), all is well. Something(s) was/were missing in the 3.5.0 kernels vis-a-vis ATI/ATI-hybrid graphics. I say that as these kernels performed admirably with -Intel graphics (both -Arrandale Integrated and, surpisingly, my old -855). I do not have an Nvidia platform, so no observation there. One last note: prior to the 3.5.1/3.5.2 kernels, I tested the -krm-radeon-desktop (jobermayr's kernel libs). The -drm's seemed to improve the performance of the ATI graphics, but only lengthened the MTTF by about 10 minutes. End result was either the CPU lockup or panic. Once I am satisfied with the stability of the 3.5.2 kernel, I may revisit that ATI -drm. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
