Nouveau - Feb 2018 - [Bug 105045] New: System freeze with nouveau

https://bugs.freedesktop.org/show_bug.cgi?id=105045

            Bug ID: 105045
           Summary: System freeze with nouveau
           Product: Mesa
           Version: 17.3
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: serg.partizan at gmail.com
        QA Contact: nouveau at lists.freedesktop.org

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?

This happens because GPU fault recovery currently leaves the process in a
totally broken state. (And all other processes that use the GPU, seemingly.)

The general approach has been to try to avoid the GPU faults in the first place
-- that will be printed before any of your other errors (i.e. before the
nv50_cal stuff).

Note that mesa 18.0 may have some relevant fixes, e.g. 

commit adcd241b563f44b2e3e92f5d840e2f617bc25836

    nvc0: ensure that pushbuf keeps ref to old text/tls bos

Perhaps worth a shot. (This could hit if gnome-shell were generating tons and
tons of silly shaders. Which it might be.)

You can just apply it. There's other stuff that's gone in though... I
was just
pointing out one thing I did. A bunch of people had issues with 17.3 and
resizing stuff as I recall... other things too. I'd basically recommend
running
mesa master -- mesa is not very good at backporting fixes. And master's very
rarely in a broken state.

I found there is also 18.0.0-rc4, and looks like it almost recently released.
I just built it, it working but now i can't click anything with mouse nor
gdm
nor after login into gnome-shell.

But under weston it is working.

Switching from wayland to xorg fixed issue with mouse in gnome. But issues with
xorg it is what get me to use nouveau+wayland (under xorg there is broken
keyboard switching using grp:shift_caps_switch).

I built mesa-git from source, and gdm starting only in xorg mode.

When i try to run
> XDG_SESSION_TYPE=wayland exec dbus-run-session gnome-session
It fails with message "Connection to the bus can't be made"

weston is still running fine.

reverted back to 17.3.3

After updating to mesa 17.3.5-1 i haven't seen this bug for few days.

Looks like it was fixed.
