--- Comment #20 from drrossum <d.r.vanrossum at gmx.de> ---
Just did this test.  It produces exactly the crash that I experienced with
version 907:

[ 1540.594567] [drm] Manually setting wedged to 1
[ 1540.594580] [drm] capturing error event; look for more information in
/sys/class/drm/card0/error
[ 1541.099920] [drm:i915_reset] *ERROR* Failed to reset chip.

I can revive the GPU by putting the whole system to sleep and wake-up again.

I guess that means that this bug is not resolved yet, but as long as the GPU
doesn't hang the driver doesn't try to reset and this bug is not triggered.
