Binary package hint: xserver-xorg-video-intel
Hi
Found the screen black with the backlight turned on when opening the lid
this morning (lid was closed, but computer wasn't suspended); the seqno
wasn't increasing in /sys/debug, so I think it's a GPU lockup.
Loïc, the GM45 should reset itself when it detects an error, but in your
dmesg I can't see any error from drm (normally it's either Hangcheck
timer elapsed... GPU hung or render error detected). You can increase
the verbosity and display any messages from a reset with drm.debug=0x02
as kernel
I've updated my kernel cmdline to include the drm debug stuff, but I'm
less keen on running a 2.6.33 kernel; I realize this might help
debugging the upstream issue against tip, but I'm not sure what it
implies for other packages on my system.
