/sys/class/drm/card0/error
I get this crash from time to time, without any clear way of reproducing it.
I've seen it twice in a row today. I think it only happens when connecting an
external monitor via a docking station (and turning off the built-in display).
My GPU is an Intel® HD Graphics 520 (Skylake GT2):
VGA compatible controller [0300]: Intel Corporation HD Graphics 520 [8086:1916]
(rev 07)
This is on Fedora 25 with kernel 4.11.6-201 and xorg-x11-drv-intel
2.99.917-26.20160929.
