/sys/class/drm/card0/error

The following occurred on my Lenovo T520i laptop when I was trying to move my mouse cursor in KDE Konsole (on Xorg) while an emerge to update miscellaenous packages was almost finished in the background. It has a Nvidia GPU, but that was disabled in UEFI.

[ 3002.958826] mce: [Hardware Error]: Machine check events logged
[ 3041.008942] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off
[ 3101.058104] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

[ 3759.553756] [drm] GPU HANG: ecode -1:0x00000000, reason: Kicking stuck semaphore on render ring, action: continue
[ 3759.553763] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 3759.553764] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 3759.553766] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 3759.553767] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
