          Priority: medium
            Bug ID: 58959
          Assignee: dri-devel@lists.freedesktop.org
           Summary: kernel 3.6.4 and r600_dri.so from mesa 8.0.5 are
                    incompatible
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: aaalmosss@gmail.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

It results in massive amounts of this printout:
radeon: The kernel rejected CS, see dmesg for more information.

dmesg says:
[  824.623357] radeon 0000:01:00.0: evergreen_surface_check_2d:285 cb height
1088 invalid must be aligned with 128

[  824.623365] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !


I've got the kernel from vanilla source, and mesa from package (debian
unstable). Mesa 9.1-dev works fine. I've got libdrm 2.4.40+ from git
(0980633afd9c7eecc0c75ef3bea4d3c6b7aa1898) installed in /usr/local/lib.

--- Comment #1 from Alex Deucher <agd5f@yahoo.com> ---
xf86-video-ati 7.0.0 enables 2D tiling by default and hence requires mesa 9.x. 
You either need mesa 9.x, or you have to disable 2D tiling:
Option "ColorTiling2D" "False"
in the device section of your xorg.conf

Oh, in that case I guess normal debian users are safe from this problem,
because in 6.14.4 it is off by default. Closing as PEBKAC.
