normal kernel better than rt kernel on hardy?

[atuc]

hallo,

i am really astonished, i tried both the hardy rt kernel and the
standard kernel 2.6.24-16-generic and i get no xrun on the standard
kernel with 34.8 ms latency,

the realtime kernel 2.6.24-16-rt produces xruns every 30-60 sec. with
the same parameters??

does anybody know why? as i remember the feisty 2.6.22-14 rt kernel
worked better with about ~ 10 ms latency on my macbook an my usb m-audio
fasttrack pro.


my jackd:
/usr/bin/jackd -R -P89 -p512 -t2000 -dalsa -r44100 -p512 -n3 -D -Chw:4,1
-Pmulti

best,
alex
