I will look into this.

nothing obvious. If there is really blocken lock, could you please enable lockdep |CONFIG_LOCK_DEBUGGING_SUPPORT=y |CONFIG_PROVE_LOCKING=y |# CONFIG_LOCK_STAT is not set |CONFIG_DEBUG_RT_MUTEXES=y |CONFIG_DEBUG_SPINLOCK=y |CONFIG_DEBUG_MUTEXES=y |CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y |CONFIG_DEBUG_RWSEMS=y |CONFIG_DEBUG_LOCK_ALLOC=y |CONFIG_LOCKDEP=y |# CONFIG_DEBUG_LOCKDEP is not set |CONFIG_DEBUG_ATOMIC_SLEEP=y

and send me the splat that lockdep will report?

I will do so. I cannot promise, however, that this will happen within the next few days.

Thanks for your suggestions, Soeren
