The gpu crash dump
>From time to time, (once every couple hours approximately), the graphics system
hangs for a few seconds, then returns to normal.
The output from dmesg at the time is:
[feb27 19:52] [drm] GPU HANG: ecode 7:0:0x85dffffc, in kwin_x11 [3775], reason:
hang on rcs0, action: reset
[ +0,000002] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ +0,000000] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ +0,000000] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ +0,000001] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ +0,000001] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ +0,000043] i915 0000:00:02.0: Resetting chip for hang on rcs0
Thanks a lot.</pre>
