0d0b3e7443bed6b49cb90fe7ddc4b5578a83a88d is the first bad commit commit 0d0b3e7443bed6b49cb90fe7ddc4b5578a83a88d Author: Jerome Glisse jglisse@redhat.com Date: Wed Nov 28 13:47:55 2012 -0500
drm/radeon: use cached memory when evicting for vram on non agp
Force the use of cached memory when evicting from vram on non agp hardware. Also force write combine on agp hw. This is to insure the minimum cache type change when allocating memory and improving memory eviction especialy on pci/pcie hw.

--- Comment #11 from Serkan Hosca serkan@hosca.com --- No change with linus git rc3 as of today + drm-fixes-3.8 with mesa at e09a5846cdab01a3bf04ac8c11e352d85b89b4af and -ati at 102ee4a24e4c9ba0c0b65d3ca8599dc7e0216c1e. It floods the dmesg after login and computer freezes.
I tried switching to gdm but i dont't even get to the login screen, computer freezes.
I tried openbox, i was able to login and ran glxgears, some 3d screensavers but the computer froze when i tried some webgl demos. I saw a couple of: radeon: The kernel rejected CS, see dmesg for more information in the terminal and the same dmesg flood and the computer freezes.
