Error log from /sys/class/drm/card0/error

Random hang when resizing a window.

"sudo dmesg" told me to file a new bug report:

[ 5599.030950] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [1101], reason:
Hang on rcs0, action: reset
[ 5599.030952] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 5599.030952] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 5599.030952] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 5599.030952] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

Sadly, I don't know how to reliably reproduce this.
