GPU crash dump

With Linux-4.16.6 on a Lenovo X1 laptop (Skylake GT2 [HD Graphics 520]) I just
hit the following:

[   24.801885] [drm] GPU HANG: ecode 9:1:0xfefffffe, in Xorg [600], reason:
Hang on bcs0, action: reset
[   24.801886] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   24.801886] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   24.801886] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   24.801887] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
