Created attachment 135690 [details] /sys/class/drm/card0/error Occurs in both X11 and Wayland (Gnome for both) under Ubuntu 17.10 typically when playing video (either via Totem or FireFox). Netflix on FireFox v57 seems particularly good at triggering a lockup which the kernel does not recover from (hard reboot via power key required). Output from /sys/class/drm/card0/error attached. Ubuntu 16.10 and 17.04 didn't seem to cause this type of issue (even with Gnome on Wayland).
