Hi,
I've done all the optimizations recommended by the
realtimeconfigquickscan script detailed here below.
I followed all the recommendations included in the jackaudio.org FAQ.
I've recompiled my own rt kernel from peguntronix and kernel.org also.

I'm also get xruns with the system without load and I've observed that
just disabling the wifi network helps a lot and no more xruns are
observed.

I'm using ubuntu 9.10 with Jack1 and a cheap (but decent) Behringer
UCA202 audio i/f.

Bye

Do you know if your wifi card is sharing an interrupt with your audio interface?

On my laptop the nvidia card was sharing an interrupt with the firewire interface. After enabling MSI in the nvidia driver my xruns became non-existent. Maybe you have this option with your wifi module.
