Hi,
29-4 with PREEMPT works very good (jackd at 64 frames: 0 xruns (running for 1h now), soundcard irq unthreaded). Opposed to 29-1 PREEMPT_REALTIME which showed some very weird jackd behaviour (xruns from 10usec to 50msec [!!!]). rtc_wakeup was showing no large jitter for that kernel though, nor did the different traces show anything that might have caused the jackd xruns. And yes, i configured the irq handlers sanely :)
Will build 29-4 PREEMPT_REALTIME now and see how this one behaves.
