Description Stefan Dösinger 2012-07-20 14:37:04 UTC

Since Mesa commit 30257c32910c3f7ac2b9cc24399d6be196d34d26 r600g fails to render anything on Linux 3.3 and probably all earlier versions. An upgrade to 3.4 fixes the issue.

The output from glxinfo is:
radeon: The kernel rejected CS, see dmesg for more information.

This is accompanied by the following lines in dmesg:
[199859.400626] radeon 0000:01:00.0: forbidden register 0x00028b28 at 188
[199859.400628] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

My understanding is that Mesa is intended to remain backwards compatible with older kernels. If this is not the case feel free to close the bug.
