Regarding the original subject of the post: Running startx with the nvidia binary driver fails on 3.0.9-rt25 and 3.2-rc2-rt3 when CONFIG_PREEMPT_RT_FULL=y and works fine for CONFIG_PREEMPT_RTB=y. There is no lockdep-warning, kernel oops/bug, etc., neither in any log-files nor on the serial console. This happens on several machines which ran fine with 2.6.33-rt29. I know many people here are no big fans of the nvidia driver (and rightly so). Unfortunately we really need this. If anyone has any further ideas on debugging this issue I would be really thankful.
