Created attachment 45860 [details] kernel traces for GPU lockup OpenGL renderer string: Gallium 0.4 on AMD RV710 OpenGL version string: 2.1 Mesa 7.11-devel (git-c98fa6b) After finishing loading any level game shows black screen (like monitor goes off), than screen goes back to live filled with some flickering garbage. netconsole on other hosts reports GPU lockup traces from kernel. Leaving game in this state for a while leads to complete kernel hangup. I failed to reproduce this on any other non-native 3d-application (read: game), neither on any native (still, I don't have access to much of them). Changing various in-game settings to lowest possible doesn't help, nor switching dxlevel (they seems to disable this feature). Attaching traces log from netconsole. I may also attach wine output, as it contains information about GL calls, but maybe it will be better to post wine bug for this? If there is any way to get some error-state (like one from intel cards in similar bugs here) or opengl calls trace - I'll happily provide them.
I have ArchLinux x86, Radeon HD 4850 OpenGL renderer string: Gallium 0.4 on AMD RV770 OpenGL version string: 2.1 Mesa 7.11-devel (git-bd661a9) I have similar error in Portal & Portal 2 game.

This seems to be a problem with all games that use the HL2 engine in its DX9 level mode. Portal seems to force dxlevel >= 90 and therefore always produces this lockups.
This might be the same as bug 36812. Can you try reverting the commit mentioned there and see if it still hangs?
This issue was already present long before this particular commit, at least for me. It's also not strictly related to the HL2 engine, since I get the exact same problem with FEAR and its DX9 level renderpath. I presume that r600g currently doesn't handle shader code that well that gets build by wined3d for certain shader configurations.
The hangs in Team Fortress 2 and Left 4 Dead has been fixed on git master now, can you retest?
I have not tested it for a long time and I can't say when the error is gone. mesa-8.0 & mesa-git no error on ArchLinux x86, Radeon HD 4850. Tested Portal, HL2 (Episode One/Two), Team Fortress 2, Left 4 Dead 2. Can this be closed?
Please reopen if this is still an issue.
