backtrace at the time of the hang

I'm having X hangs, more or less at random. Killing X results in wedged hardware and a reboot is necessary.

I'm not using KMS.

Xorg log after hang

Comment 3 Eric Anholt 2009-05-09 08:07:25 UTC

Backtraces are never useful for GPU hangs.  But intel_gpu_dump output could be very useful.

Comment 5 Sven Arvidsson 2009-05-09 14:14:22 UTC

Output from intel_gpu_dump after such a hang is attached.

Comment 6 Jesse Barnes 2009-05-11 11:21:59 UTC

Adjusting severity: crashes & hangs should be marked critical.

Thanks for the dump!  Looks like another copy of #21488.
