realtime but this does not change the warnings/xruns. It's not the first time I setup a computer for audio and so far succeded using 64 frames/period. Here I tried every settings I could
(periods/buffer, samplerate, even tried with a Maudio Fast track pro) but still no joy.

Maybe this helps:
Using a 2.6.24-rc5 kernel with jackd @builtin hda intel soundcard:
$ jackd -t100 -RP 80 -d alsa -d hw:0 -p128 -n3
The -t100 and the -n3 took me some time to find out.
With em the only thing noticed so far to stall jackd was $ lsusb.
