[Bug 65764] i915 hangcheck

--- Comment #4 from Martin Weinberg <martin.weinberg at comcast.net> ---
I've been fighting with this problem since 3.8.x and appreciate that the latest
kernel (3.10.x) seems to have this well under control.  In particular for
3.8.0, pounding heavily on the drm causes hang checks that require an X restart
or a full reboot.

With 3.8.3 and esp. 3.10.x the hangs are more gracefully handled (yay!) but
they still occur.  I can reliably (although still randomly) cause a GPU hang by
running three glxgears and then watching a youtube video at HD res.
