Starting with "drm/radeon/kms: r600/r700 command stream checker" I get lock up on every init 5 (KDE in my case) start. I can start in init 3 (with KMS) but that's it.

Jerome sent an updated version of the CS checker to dri-devel this morning.
I reported this issue after testing on my Sone VAIO FW11S which has Mobility RV620. I also have access to Samsung R522 with Mobility RV730 (M96).
I've just tried current drm-radeon-testing which contains:
drm/radeon/kms: r600/r700 command stream checker
drm/radeon/kms: fix r600/r700 cs checker to avoid double kfree
starting X on this machine (and so starting KDE 4.3 with OpenGL effects) causes lock up.
Hm, the same drm-radeon-testing seems to work here. Standard KDE, KDE OpenGL effects, glxgears, OpenArena, Xv. Didn't experience lock up.
With updated git it works fine already, some additional fix gone into tree. Thanks.
