Gpu crash dump and Xorg log
I am running a debian/sid linux on a laptop with an optimus nvidia card
(nvidia GeForce GT 640 2GB) using the NOUVEAU driver.
>From time to time kwin crashes.
Also, while running, the cursor sometimes turns to a 2cm X 2cm white block.
Following is the message from dmesg.
The GPU crash dump and the Xorg.0.log is attached.
---------------------------------------------------------------------------
[ 2322.266868] [drm] stuck on render ring
[ 2322.266887] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 2322.266888] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2322.266889] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2322.266890] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2322.266891] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
