[Bug 946899] Re: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
I can consistently reproduce the "*ERROR* Hangcheck timer elapsed... GPU hung" message in the following conditions: using the new Google Maps interface with Chrome and WebGL hardware acceleration enabled. After a few seconds navigating in the Maps interface, the browser crashes and Unity freezes. I'm able to restore Unity by switching to the terminal, killing Compiz and switching back again. After restoring Unity, it seems that Chrome automatically disables hardware acceleration. You can see, attached, the results of about:gpu before and after the crash. After this point, Maps navigation does not crash the browser. However, by restarting the browser, hardware acceleration is back again, and I'm able to reproduce the same behavior. ** Attachment added: "gpu.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/946899/+attachment/3893775/+files/gpu.tar.gz -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to a duplicate bug report (644740). https://bugs.launchpad.net/bugs/946899 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

I also have sometimes hangups where CTRL+ALT+F1 and afterwards CTRL+ALT+F7 brings back GUI response, but very rarely. I am using Chrome only for Hangouts, for everything else I am using Firefox.

Re: [Bug 946899] Re: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
Thanks, peterbo. Sorry, got confused. Of course, I'm running it on 13.04, too. I have had these really weird crashes before (rebooting by itself) and they went away after one of the kernel upgrades, maybe even when upgrading from 12.10 to 13.04. Got the Hangcheck timer elapsed ones instead. That is, sometimes, when I return to my laptop, it is turned off even when I'm pretty sure I left it on, so maybe they have just been happening while idle. Now with the rc5 kernel I got the original crash (without error log) within hours again, so I got discouraged from trying any further. It's my work laptop, running dual monitors, and I really can't afford to experiment too much as I need it to run and do its job. I still can't believe that this is such a persistent bug (several bugs?). The Linux kernel used to be considered bomb-proof! Apparently its bugs, too...

I've been running Ubuntu 12.04 for over a year now without problems on my home computer, but since about a week ago when I ran the update installer, the graphical system has started to crash randomly as described in this bug report. Symptoms (appear randomly, only one at the time): - System freezes completely during late stages of startup. Reboot recovers. - System might start and everything work, but Apport dialogs appear one after another. Even if you complete the the Apport report, new dialogs about the exact same Intel GPU problem reapper. Reboot recovers the insane Apport loop. - During use window decorations disappear. Window contents partially respond to mouse, but as the window manager seems dead, system must be rebooted to recover.

This is likely a firmware bug on this device. Contact the card vendor for a firmware update. The HDMI hot plug event is part of the bug.

Just a small "happens to me to" comment, with one small extra detail about kernel versions: After Ubuntu 12.04 with automatic updates picked up kernel 3.2.0-39-generic, all computers on our campus (20+ with the problem) with Pentium G840 for CPU (Intel i915 graphics) started having that problem. We resolved the problem temporarily by installing linux- image-3.2.0-38-generic and removing linux-image-3.2.0-39-generic. The old fix described in the kernel bug report was not working for us (kernel command line option i915.i915_enable_rc6=0) -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to a duplicate bug report (644740). https://bugs.launchpad.net/bugs/946899 Title: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

For completeness, below an example from the syslog under Kernel 3.8.2 (again needed emergency reset). I also tried Kernel 2.6.38-13, which did not result in the same "GPU hung" message, but lots of other crash reports, so I gave up quite quickly.

[Bug 946899] Re: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
Just to give an idea of the frequency of the GPU hangs, I pasted below a part from my syslog. After the 3rd hang in a row, the system became unresponsive and I had to do an emergency shut-down (Alt+SysRq, R, E, I, S, U , B). Hope this will help with the troubleshooting.
