GPU crash dump saved to /sys/class/drm/card0/error

The display stopped responding for a little while, so I checked dmesg
and the drm system asked for a bug report. Hasn't happened before.
First boot of kernel 5.3.8.

~ $ uname -r

[   73.208312] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   73.208312] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   73.208312] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   73.208313] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
