Observation:
============
With Hawaii acceleration enabled (including drm) I just got a gpu reset that
failed to recover. It happended when I closed a gwenview window after a few
hours of use (window manager was cinnamon). After going black and switching off
for a while, the screens (2x DVI and 1x HDMI) came back, but displayed only
flickery noise (I could see where the mouse pointer would've been as a
differently noisy rectangle, and could move it). I could still ssh into the
machine and aquire dmesg and Xorg.0.log.
Interesting messages from dmesg:
[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[drm:atom_execute_table_locked] *ERROR* atombios stuck executing C466 (len 254,
WS 0, PS 4) @ 0xC490
