Public bug reported:
These GPU hangs seem to occur when using firefox along with other
applications. Although it is not reproducible, or at least, I have not
been able to find a recipe for introducing it.
In this case, the GPU recovered. In many cases it does not.
The relevant lines from the syslog seem to be:
[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[100824.307518] [drm] capturing error event; look for more information in
/debug/dri/0/i915_error_state
I have attached the i915 error state.
