           Summary: System freeze with nouveau
           Product: Mesa
           Version: 17.3
          Hardware: x86-64 (AMD64)

dmesg after  crash

I use ArchLinux with latest updates:

- linux 4.15.2-2
- mesa 17.3.3-2
- wayland 1.14.0-1
- wayland-protocols 1.12-1
- gnome-shell 3.26.2+14+g64c857e3f-1

And Nvidia GTX 1080 hardware.


My system sometimes freezes when i open new tab in gvim. It does not respond to
Ctrl+Alt+1-7, so i cannot switch to terminal. But it reacts to REISUB, which i
used until today.

Today I connected to desktop via ssh, used `strace` to connect to Xwayland, and
it was doing over and over something with DRM_IOCTL_NOUVEAU_GEM_PUSHBUF.
I forgot to save that log, i will include it next time.

Then i killed process with `kill -QUIT`, and it saved coredumps from Xwayland
and gnome-shell. After that gdm restarted and everything was fine.

Attaching dmesg and coredumps. What else can i do to help fix this bug?
