Journal (fifo read fault and drm_crtc.h)

Reading a bit more into the kernel log, I see that the drm_crtc.h warning might
have been triggered by nouveau after all, because above that I have:

nouveau 0000:01:00.0: fifo: read fault at 6ff792f000 engine 07 [PBDMA0] client
06 [HOST] reason 00 [PDE] on channel 31 [023e0c9000 xembedsniproxy[2833]]
nouveau 0000:01:00.0: fifo: fifo engine fault on channel 31, recovering...
------------[ cut here ]------------
WARNING: CPU: 0 PID: 4 at
../drivers/gpu/drm/nouveau/nvkm/engine/fifo/gk104.h:73
gk104_fifo_recover_work+0x22a/0x290 [nouveau]()

Attached the systemd journal of this. The warning above is at line 1834. The
Xorg.0.log file does not have any errors or warnings at all.

I'm not sure if this should be a yet another bug report?
