when loading the 'radeon' driver with modeset=1 (KMS enabled)
the following error appears in dmesg | grep drm
[drm:r100_ring_test] *ERROR* radeon: ring test failed (sracth(0x15E4)=0xCAFEDEAD)
[drm:r100_cp_init] *ERROR* radeon: cp isn't working (-22).
the result is that OpenGL renderer with be the 'software rasterizer'. and performance is obviously crippled.
OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer
OpenGL version string: 2.1 Mesa 7.8.1
The error occurs with kernels 18.104.22.168, 22.214.171.124 and even the latest at the time 2.6.36. The pc is a toshiba satellite m40-185 laptop with ati mobility radeon X300 (rv370) gpu.
Additionally, I have tried installing the git versions of libdrm, mesa, and xf86-video-ati to this date (29/10/2010) with Gallium support (enabled in turn --enable-gallium, --enable-gallium-radeon and even both, using llvm (version 2.8) compiler. The problem persists.
The only way to get 3d accelaration is to disable KMS. then dmesg | grep drm seems to load up fine (see here: http://pastebin.com/vNfyeq7P). But then I have problems with 3d applications 'competing' to stay on top - they don't seem to be able to work well with KDE4 compositing effects. To avoid that I have to disable the compositing effects ( see here for in depth explanation and some Xorg.0.log and dmesg outputs http://www.linuxquestions.org/questions/slackware-14/3d-applications-compete-to-stay-on-top-with-the-radeon-driver-840392/ )
Is this still and issue with current kernel ?

Max: ping? How do current kernels behave?
