Hmm - blacklist the wifi drivers? I understand that even when you're
not connected, they will still regularly scan for signals. I
understand this can take time and is not RT-friendly at all.

I have a dual-core netbook (non-RT kernel, it's borrowed). During the
day, it sits on my desk at work and plays music from a USB drive thru
my UCA-202 USB soundcard. When I close up at the end of the day, JACK
will show 9-11 xruns.

i have some not so nice drop-outs in playback, which not seem to be

tried to debug a bit, but could not find any errors in kernel- or device

does anyone know a good practice how to filter this?
thanks james for that hint.

Interesting! I'm also loking  for a USB 2 interface and the KA6 seems
to fit my needs. It is advertised as being capable of very low
latencies. Did you have any experience of this on linux ?

        I have a 2i4 - it only has 2 inputs though (as the name
        suggests). It
        is an excellent device overall, but I have been having some
        serious
        teething troubles with kernel releases over 3.5. I am
        providing bug
        reports to the kernel devs and these problems (not being able
        to start
        at low latencies, audio system locking up) seem to be slowly
being
        addressed, but performance is not quite there yet for me, and
        I would
        suggest if you decided to get one of these devices, and are
        affected
        by these bugs, you might experience less pain using the
        earlier 3.5
        series kernels for now. I think that this problem is not just
        limited
        to the scarlett devices, and that other USB audio devices
may be
        similarly affected. Also, I think these issues may also be
        USB-hardware (or BIOS?) dependent, so some people with the
        same kernel
        and audio device may not experience the same bugs.
