GPU crash dump

A part of dmesg output:

[ 1756.813290] [drm] GPU HANG: ecode 9:0:0x84dffff8, in Xorg [1122], reason:
Hang on render ring, action: reset
[ 1756.813291] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 1756.813292] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 1756.813292] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1756.813293] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 1756.813293] [drm] GPU crash dump saved to /sys/class/drm/card0/error
