I tried latest development release and there were no problems during about 1 hour of OS activity. I hope I try to test it longer in a few days.
What about video driver: I use radeon, below there is an output of command dmesg | egrep 'drm|radeon' [ 1.913046] [drm] Initialized drm 1.1.0 20060810 [ 2.167585] [drm] radeon defaulting to kernel modesetting.
