GPU crash dump

Extremely frequent GPU hangs that lead to a system crash on Fedora 25 running
on Lenovo T460s laptop. Example of dmesg output:

[  810.770373] [drm] GPU HANG: ecode 9:0:0x86dffffd, in Xorg [1361], reason:
Hang on render ring, action: reset
[  810.770376] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  810.770377] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  810.770378] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  810.770379] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
