.. and apparently a lot of breakage too. My crappy laptop that I abuse
for travel is - once more - broken by the updates. I cannot suspend
and resume, because every resume seems to fail.
One of the more useful failures was:
[ 61.656055] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer
elapsed... GPU hung
[ 61.656079] [drm] capturing error event; look for more information
in /debug/dri/0/i915_error_state
[ 61.664387] [drm:i915_wait_request] *ERROR* i915_wait_request
returns -11 (awaiting 2 at 0, next 3)
and I'm attaching the error_state file from that particular case here.
In other cases it seems to just hang entirely.
Keith/Jesse/Chris - I don't know that it's i915, and it will take
forever to bisect (I'll try). But it does seem pretty likely.

Why can't the gpu be reset/restarted when this happens? When a nic card
gets hung it is reinitialized
and restarted why not the gpu?
