GPU crash dump
Running Fedora 25 on a Intel NUC 6i5SYH with Intel Iris Graphics 540 causes GPU
hangs at right after the boot (gdm). It happens always, no chance to login.
[ 304.645809] [drm] GPU HANG: ecode 9:0:0x85df7efb, in Xorg [13399], reason:
Hang on render ring, action: reset
[ 304.645812] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 304.645814] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 304.645816] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 304.645818] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I tried to disable wayland and play around with different xorg config.
Using "intel" as a driver did never work. It only works with the following
config (but without hw acceleration):
Section "Device"
Identifier "Intel Graphics"
Driver "modesetting"
Option "AccelMethod" "uxa"
EndSection
