Description:
After some time of normal use of Gnome Shell with nouveau driver the screen
gets frozen and I have to restart the GS from another TTY.


Additional info:
xf86-video-nouveau 1.0.10-2
xorg-server 1.15.0-5
linux 3.12.9-2
I use nVidia GeForce 8200
I'm including Xorg.0.log and outputs from dmesg, `journalctl -b` and
`journalctl --since=${time_of_freeze}`


Steps to reproduce:
This behavior seems to happen randomly.

To me, this reads like "you ran out of vram and the driver did not handle this
at all gracefully". "Unhandled ustatus 3" means "FAULT" as best I can tell. And
of course since gnome-shell also acts as a compositor, that means your display
is shot.

The question is how can this happen though... I guess something was requested
to be migrated to vram and that request failed, but the driver didn't notice?
Not sure. Your second log shows a pushbuf submission failure that caused a
validate fail. I don't remember if that means that something was claimed to be
in VRAM and wasn't or if it means that something was requested to be moved to
vram and the move failed.

The fact that you can even go to another TTY and restart GS indicates that the
card is in no way hung, which is nice.

You don't mention what version of mesa you're using... but I'm assuming
something pretty recent, like 10.0.3 or maybe even 10.1-rc1?

Yes, I forgot to mention Mesa version, it is 10.0.3-1 on Arch Linux.

The above comment is missing a description. Here it is:

On my system (ARCH) I run to texture problems on gnome-shell with very similar
errors.
When I have a certain amount of widgets open, the task switcher shows black
squares instead of previews of my widgets.

Used versions:
- xf86-video-nouveau 1.0.10-2
- mesa 10.1.4-1
- nouveau-dri 10.1.4-1
- libdrm 2.4.54-1
- Linux 3.14.4-1 x86_64

So I resigned on using Nouveau and went back to nVidia, specially its 304xx
version on Arch Linux. 

local/lib32-libcl 1.1-1
local/lib32-libvdpau 0.7-2
local/lib32-nvidia-304xx-libgl 304.121-2
local/lib32-nvidia-304xx-utils 304.121-2
local/lib32-opencl-nvidia 337.19-1
local/libcl 1.1-3
local/libvdpau 0.7-1
local/nvidia-304xx 304.121-3
local/nvidia-304xx-libgl 304.121-2
local/nvidia-304xx-utils 304.121-2
local/opencl-nvidia 337.19-1


I'm also using these Mesa libs:
local/glu 9.0.0-2
local/lib32-glu 9.0.0-2
local/lib32-mesa 10.1.3-1
local/lib32-mesa-demos 8.1.0-3
local/mesa 10.1.3-1
local/mesa-demos 8.1.0-2

I also had this bug on Arch Linux with my onboard GeForce 7300. I increased the
shared memory in the BIOS settings from 256M to 512M and problems are gone !
