drm from today morning drm git (drm.ko and radeon.ko) cause kernel (2.6.25rc5
from git) oops, repeatable every time.
xserver 1.4.0.90
mesa 7.0.2
ati driver from recent git
01:00.0 VGA compatible controller: ATI Technologies Inc M24 1P [Radeon Mobility
X600]
In-kernel (2.6.26rc5) drm works fine, so something is broken in mesa/drm git
tree.
