This has put me a couple of weeks behind schedule, and I just don't seem to have an answer.  I don't seem to have a problem when I don't use the realtime kernels.  But I see lots of xruns with jack. Which brings up another question.  Can I make some decent multitrack recordings WITHOUT using the realtime kernel (I"m using a Pentium D dual-core CPU running at roughly .2.8 gigahertz, 2 gig of RAM).   Or do I HAVE to have the realtime kernel.

Do you really need low latency?  If you're only using ardour as a hard
disk recorder, set your jack buffer size large enough (>= 1024 maybe?)
so that the xruns disappear.  You only need low latency if you're
doing something like software monitoring.
