Bug 34359

Hi,

(I'm reproducing this from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=613596 as suggested by Julien Cristau.)

Hi,

Since upgrading to libgl1-mesa-dri 7.10 with the Gallium driver, GL applications (e.g. xmoto) either suffer texture corruption or cause GPU lockups, sometimes recoverable, sometimes not. I haven't been able to get a screen capture with texture corruption; in xmoto for instance the red buttons have white lines through them.

Whether the game works with texture corruption or causes GPU lockups seems to be decided at launch time, i.e. if the game launches it doesn't crash later, but if it causes a GPU lockup it never gets to display anything. Killing the game sometimes allows the system to recover; in other instances it's necessary to reboot.

I tried running with mesa rebuilt from git master, and encountered the same problems.

When the GPU locks up, the Oops is as follows:

Let me know if you need any more info, or if you want me to try patches etc.

This could be https://bugs.freedesktop.org/show_bug.cgi?id=31532 but since similar symptoms don't always imply the same bug, I'll leave it up to you experts!

Regards, and thanks for your time,
