on SMP i had to remove this assert:

Index: linux/kernel/rtmutex.c
===================================================================
--- linux.orig/kernel/rtmutex.c
+++ linux/kernel/rtmutex.c
@@ -823,7 +823,7 @@ rt_spin_lock_slowunlock(struct rt_mutex 
 	}
 	wakeup_next_waiter(lock, 1);
 	spin_unlock_irqrestore(&lock->wait_lock, flags);
-	BUG_ON(current->boosting_prio != MAX_PRIO);
+//	BUG_ON(current->boosting_prio != MAX_PRIO);
 	/* Undo pi boosting.when necessary */
 	rt_mutex_adjust_prio(current);
 }

because it triggered almost immediately after bootup.
