[Problem]
GPU hang with call trace in dmesg occurs subsequent to full screen activity (video playback); also seen by other users after resuming from screen blanking via DPMS and after resuming from screensaver.
[Original Report]
I had finished watching a video in totem, and had been writing email using mutt and vim in a terminal for some time, when the screen stopped updating. My music was still playing, though; everything seemed to be running except for the X server (symptoms similar to bug 359392).
I was able to ssh in from another system and collect intel_gpu_dump output, which i will attach.
/proc/interrupts showed no change in the number of interrupts for i915.
The kernel logged a page allocation failure while intel_gpu_dump was running(!), which will be shown in the attached dmesg.
I've seen it happen twice now (in the span of 2 hours), and both times, dmesg shows the above trace.
