Thanks for your help,

Ok well I seem to still get the zombies.  I got the rtirq script and I
*think* it's working.  I configured it just like the freebob site says

output from "rtirq status":

I used "/proc/interrupts" to show the irqs, specifically noted IRQ 16
16:        741   IO-APIC-fasteoi   uhci_hcd:usb1, ehci_hcd:usb5, ohci1394, HDA
Intel, i915 at pci:0000:00:02.0

It seems that my firewire device is sharing an IRQ with a couple usb
ports, the internal soundcard and internal video.  My guess is that
this isn't good.  Should I attempt the give the firewire it's own IRQ
and if so, could you point me in the direction of how to do that?  I'm
figuring this stuff out as I go here so it's hard to know how to
proceed sometimes.

Also, when setting the jack priority do I want it to be just under the
firewire device?  for example:  if IRQ 16 was just the firewire
(running at 75), then running jack at 74 would make sense?
