Kernel log
Environment:
- Linux kernel 4.5.4
- Desktop environment: Gnome 3.20.2
- Xorg 1.18.3
- Graphics card: NVIDIA Corporation GK107GLM [Quadro K1000M] (rev a1)
Nouveau makes Xorg unresponsive after resuming from suspend to RAM. Restarting
Xorg did not help, but a reboot.
Error messages look like:
nouveau 0000:01:00.0: fifo: read fault at 0000dc8000 engine 15 [CE0] client 01
[CE0] reason 02 [PTE] on channel 0 [007fd56000 DRM]
nouveau 0000:01:00.0: fifo: ce0 engine fault on channel 0, recovering...
It must be a regression, because the issue did not happen with the same
hardware on kernel 4.4.x.</pre>
