I'm also forgot to post full error: EE r600_shader.c:158 r600_pipe_shader_create - translation from TGSI failed ! EE r600_state_common.c:754 r600_shader_select - Failed to build shader variant (type=1) -1
I don't think that's quite the full output, but it does look somewhat like an issue that was fixed by commit b5ddaf9975f96c46ea3dfb02c4130de5196b238c.
