Comment # 20 on bug 958794 from andrew cooke

yay!  finally.  i was using the computer when the screen locked.  kde then
restarted.  then things became completely unresponsive.  i am attaching the
logs with a full stack dump (or whatever it is).

the text in the logs asks for /sys/class/drm/card0/error, however, that
contains only "no error state collected".
