[gm45] GPU lockup 196a8ae225e93814bc208433db407a36

[Loïc Minier]

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.

(Is there a way to reset just the GPU when that happens? -- instead of rebooting)

Thanks,

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 parameter.

It would be great if you can test the latest drm-intel-next kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ and when this happens, ssh in and grab /sys/kernel/debug/dri/0/i915_error_state, /var/log/Xorg.0.log and the output of dmesg (preferably with drm.debug=0x02).

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.
