[...] This reminds me that drm tree in linux-next still results in BSOD (Black Screen Of Death) on starting X for me (as reported on Saturday [1]). Actually there is more to it as I discovered that my custom X radeon driver (which is xorg-x11-drv-ati-6.9.0-61.fc10.i386 with "radeon: no need for this anymore" from radeon-gem-cs change reverted, please see [2] for my previous monologue) works fine while following stock driver versions: xorg-x11-drv-ati-6.8.0-19.fc9.i386 xorg-x11-drv-ati-6.9.0-61.fc10.i386 xorg-x11-drv-ati-6.9.0-62.fc10.i386 result in BSOD. OTOH they all work with next-20081128 (modulo hangs with fc10 ones when "radeon: no need for this anymore" change is not reverted). [ BTW xorg-x11-drv-ati-6.9.0-62.fc10.i386 still causes hangs when used with non-Fedora kernels and Fedora/kms kernel still has performance problems ] IOW there are a lot of compatibility issues in recent drm/radeon changes. Dave, could you please start looking into these problems? I'm sure that we all want recent drm changes + kms in 2.6.29 but given tight schedule and the way things are looking right now I'm quite sceptical...
