            Bug ID: 92922
           Summary: Xorg random freeze
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: antokara-lAq2i09A0t4Cep0kKqy/Kg@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

On Fedora (Gnome) Workstation 23, with the following:
xorg-x11-server-Xorg.x86_64   1.18.0-1.fc23
xorg-x11-drv-nouveau.x86_64   1:1.0.12-0.3.fc23
and
NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1)

At random times but suspecting Google Chrome may be causing it, 
or at least causing it to happen more easily.

The screen freezes. I have intentionally added the seconds at the Gnome Clock
to see if they will keep changing during the freeze but all the times, they
freeze as well.

The mouse moves and usually but not always, the keyboard works as well (caps
lock lights, etc.) few times I could even switch session into terminal.

From the system journal I get:
kernel: nouveau E[  PGRAPH][0000:02:00.0] TRAP ch 9 [0x023f566000
gnome-shell[2271]]
kernel: nouveau E[  PGRAPH][0000:02:00.0] GPC0/PROP trap:
ZETA_STORAGE_TYPE_MISMATCH
kernel: nouveau E[  PGRAPH][0000:02:00.0] x = 968, y = 136, format = 0, storage

kernel: nouveau E[  PGRAPH][0000:02:00.0] GPC1/PROP trap:

kernel: nouveau E[  PGRAPH][0000:02:00.0] x = 1016, y = 104, format = 0,

kernel: nouveau E[   PFIFO][0000:02:00.0] PGRAPH engine fault on channel 10,
recovering...

or just:
kernel: nouveau E[   PFIFO][0000:02:00.0] SCHED_ERROR [ CTXSW_TIMEOUT ]
kernel: nouveau E[   PFIFO][0000:02:00.0] PGRAPH engine fault on channel 10,
recovering...

and this gets repeated allot:
kernel: nouveau E[  PGRAPH][0000:02:00.0] TRAP ch 9 [0x023f566000
gnome-shell[2224]]
kernel: nouveau E[  PGRAPH][0000:02:00.0] GPC1/PROP trap:
ZETA_STORAGE_TYPE_MISMATCH
kernel: nouveau E[  PGRAPH][0000:02:00.0] x = 576, y = 512, format = 0, storage
type = fe

tried with wayland gnome session and it also happens:
kernel: nouveau E[  PGRAPH][0000:02:00.0] TRAP ch 10 [0x023f315000
Xwayland[5816]]
kernel: nouveau E[  PGRAPH][0000:02:00.0] GPC2/TPC0/MP trap: INVALID_OPCODE


Please keep in mind that the GPU is ok,
I have been using it with Windows, without any issues...

I plan to find another PC and try to SSH during the freeze, once I do, I will
post an update. Until then, the above log may be of useful to you.

--- Comment #1 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
Actually the version of mesa is the most relevant thing here. Looks like we're
somehow feeding a color surface to a zeta endpoint? That shouldn't happen :)
I'd believe the opposite... but I don't see how this happens.

[ zeta = depth/stencil buffer. storage type = 0xfe == color storage type
fallback ]

Unfortunate that you're getting this with gnome-shell... would be nice if you
could repro it with something that's easier to trace. If you're open to
building your own mesa lib, I could hack up a patch that would assert that
we're sticking zeta surfaces into the zeta endpoint, which would make any
offenders die at the point of offence.

The INVALID_OPCODE thing is unrelated -- that sounds like good ol' bad code
generated by our shader compiler, or perhaps some sort of confusion in which
code gets uploaded where. Not entirely unheard of, but haven't had one of those
in a while.

I hope this clarifies the mesa versions installed.

Now as for building the custom mesa lib, I haven't done that before.
If it's just ./configure && make && make install, I just might give it a try
;-)

You can try the patch below and see if it ever triggers. Make sure to build
with --enable-debug (otherwise you won't get the assert). You'll also probably
want --enable-texture-float (I'd check how your distro builds it and do the
same thing).

Of course note that if gnome-shell is hitting this... the assert will happen in
gnome-session and it will crash :) If you could run it in gdb and poke around
at things when it does crash that'd be useful.

It seems I have a similar issue but on kwin. I was also scrolling in Chrome
when the problem occurred (screen was frozen, I had to reboot):

Logs at the time of crash were filled with tons of:

I might be hitting this same bug with Nvidia GTX 650 Ti on Arch Linux using
released kernel 4.6, xf86-video-nouveau 1.0.12 and mesa 11.2.2

When using GNOME Shell and Chromium

maybe it's related to bug #93629 which also happens sometimes.

I am getting random freezes in different web browsers. During the freeze is
killing different kde plasma processes possible but killing xorg-server after
from ssh is not possible. I try will the assertin patch.

After switched vlc to use a non-accelerated video output I got bunch of above
messages.

media-libs/mesa-13.0.3
xf86-video-nouveau-1.0.13

mpv never caused the same type of crash, profile chosen is opengl-hq.
