Looks like the shader needs too much registers, it's probably the most frequent reason for such errors. Old backend can't handle it correctly, and I think it's not going to be fixed. LLVM backend should handle it better, so you might want to try it in this case.

I'm always think that LLVM used by default. Sorry for such silly question, but how can I determine which backend is used? I also tried to run game using R600_LLVM=1 and other env vars (with or without sb) with no change.
