GPU crash dump

Hi,

    My system is a Fedora 27 (updated) and sometimes my Xorg is crashing:

[264950.669478] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [1372], reason:
Hang on rcs0, action: reset
[264950.669482] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[264950.669484] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[264950.669486] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[264950.669487] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[264950.669490] [drm] GPU crash dump saved to /sys/class/drm/card0/error
