        <pre>More interesting fail:

[ 4366.361686] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU
hung
[ 4366.361694] [drm] capturing error event; look for more information
in/sys/kernel/debug/dri/0/i915_error_state
[ 4366.871407] [drm:i915_reset] *ERROR* Failed to reset chip.
[ 4376.364660] [drm:i915_gem_wait_for_error] *ERROR* Timed out waiting for the
gpu reset to complete


Pity we can't get the i915_error_state back, but if you can isolate the cause
of the hang that will be enough for the libva (or whoever to work on).</pre>
