Yeah, probably on PlanetEdge possibly, but really any of Fernando's
kernels should  work much better than you are reporting here. I doubt
that's the problem.

So the SB is not sharing an interrupt. That's good I suppose.

You might enable realtime in QJC and then post back the first part of
the message window where Jack is starting, just so we could get a look
at what's going on.

Is this new hardware? I just brought up a new AMD64 machine over the
last few weeks. Until last night I couldn't get it to run xrun free. I
had to build my own kernel which is not much of an issue, but it took
quite a while to find the right one to build. If you're using newish
hardware then consider trying what I built. (2.6.14-rc2-rt7) Fernando
may or may not have a good FC3 kernel yet for newish hardware.
Stanford has just started their year and I'm sure he's busy teaching
classes and keeping all those CCRMA people in line. That, and playing
in their new studio.. ;-)

Cheers,
Mark
