dmesg

When I run the game bastion there is screen corruption, and after some time the
computer locks up.

The menu renders OK-ish (with only some flickering corruption). When ingame,
the screen flickers between (mostly) uncorrupted and corrupted at random
intervals. After some time the computer crashes. Before the crash there is a
lot of output in dmesg by nouveau.

I am running archlinux.

Versions:
xorg 1.15.0
mesa 10.1.0
xf86-video-nouveau 1.0.10
nouveau-dri 10.1.0
linux 3.13.7

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Can you check with 3.14-rc8? Alternatively try booting with
nouveau.config=PCRYPT=0. (Although I'm not seeing the MMIO write error that
I
would expect to see if you had that particular issue, but it's easy enough
to
try.)

The final crash is due to running out of vram, which I guess is handled
less-than-perfectly by mesa. I'd prefer to focus on the initial corruption.

There is no change in the behaviour, with 3.14-rc8 kernel with or without
nouveau.config=PCRYPT=0.

If you capture an apitrace of the game, do you still see the corruption when
replaying the trace?

With apitrace I couldn't get past the menu without the game becoming
unresponsive, but there is already some corruption.

The trace is too big to attach, I have uploaded it at
http://blankertz.org/~matthias/Bastion.bin.x86.3.trace

As of linux 3.14.1 (mesa version unchanged) the rendering errors in the menu
are gone, the rendering errors in game are still present but the system no
longer crashes.

Attaching new dmesg.

Versions:
xorg 1.15.1
