Black textures on Linux with radeonsi

[Anorelsan]

My game isn't rendering correctly. It displays black textures. My system is:
OS: Debian SID + Mesa 10.6.8 + radeonsi (oss drivers).
Graphic card: AMD ATI R9 290.

I now that isn't right because two weeks ago my old graphic card died (an 6970) and I replaced it temporaly with an ancient nvidia 9600gt (with nouveu oss drivers) and the game was slow, but it renders ok. Now with my new graphic card and radeonsi oss drivers the rendering is broken.

In the hpl.log says that version is 3.3 so it's supported. Also there is some warning and errors.

Here a screenshot of the game with the textures problem[imgur.com].

Any help?

PD: I can post the hpl.log if needed.

Upgraded to Mesa 11 and now it works perfect!
