[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.
[drm] GPU crash dump saved to /sys/class/drm/card0/error

card0/error file attached.

Similar to bug #101991, but not the same. That bug has as a defining
characteristic the use of hibernation. This problem now happened without
hibernating, though I did suspend twice and connected to a Dell dock and to an
external monitor via USB-C.

Uptime was about 24 hours. That was my first boot using kernel 4.15. This
problem was not observed when using 4.14 and earlier kernels.
