/sys/class/drm/card0/error

Hi,

I'm using Arch Linux. I get this error message sometimes when switching from X
to tty(s) or using mplayer (xv). The X is still stable. If I set DRI to False
and NoAccel to True in xorg.conf, the message gone. But it's not a solution for
me, because of the poor graphic performance.


$ dmesg:
[drm] GPU crash dump saved to /sys/class/drm/card0/error
[21787.534947] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[21787.534950] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[21787.534952] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[21787.534954] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
