--- Comment #3 from unki at netshadow.net ---
This morning, on resuming from hibernation, system has recovered after several
GPU resets.
But only for a few minutes.
Then it locked up hard while working in X.
I've waited a few minutes if it recovers again, but finally performed a hard
reset.

I've captured dmesg and /sys/class/drm/card0/error in the short time frame
where the system was responding. I'm attaching them to this bug, in case you
note any differences in there.
