Hi, I'm trying out the latest -rt patch and getting alsa xruns when
using jackd and jack clients. This is a sample from the output of
qjackctl / jackd (jack 0.102.25, qjackctl 0.2.21):

The test machine is an Athlon X2 4400 running FC6 x86_64 booting into a
rebuilt 2.6.19-rc6-rt8 rpm package based on Ingo's packages
(same .config except for 4KSTACKS=off).

- jackd and clients running with realtime priorities
- irqs priorities reordered with the rtirq script,
this is the status after running it:

(the soundcard being used by jackd is the ICE1712, IRQ 18, jackd runs
with priority 62/72)

What follows is the output of dmesg. At the end you can find the latency
wakeup numbers. It goes back to a low value each time I reset the
counter in proc.
