<pre>I'm using Debian 9 with mate desktop 1.16.2. My cpu is a i7-7700k and I’m also
using the cpu for graphics.
But about twice a week, X become unresponsive except for the mouse but I can’t
click on anything for about 20-30secs then X restart. It close every open
program, and I lose a tons of stuff. Not sure if it has any real relation but
It usully happend while I’m moving or uncompressing files.
I found that I had multiple dmesg errors messages

[177392.090944] [drm] GPU HANG: ecode 9:0:0x84dfbffc, in Xorg [934], reason:
Hang on render ring, action: reset
[177392.090947] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[177392.090948] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[177392.090949] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[177392.090951] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
