--- Comment #4 from Michael Weitzel <miw2000-aaa at yahoo.de> ---
I had the same crash (for the first time) - also on KabyLake, ArchLinux, Kernel
4.14.15-1-ARCH. I'll attach my crash dump.

[drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [636], reason: Hang on rcs0,
action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
