Just a guess but I would imagine that for some reason the soundcard is
not delivering interrupts and eventually the watchdog notices and kills
jack (I think the timeout is 5 seconds by default). 

Are you able to play, say, a soundfile using just alsa?

You should try with the "edge" series of kernels (if they work for you).
Try installing "planetccrma-core-edge" and booting into it.

That's me, I created/[try to :-]maintain Planet CCRMA...

Just getting everything to work in the newly renovated building we just
moved in. Very busy. 

The newest kernel for fc3 still lives, I think, in the planetedge
repository. The first thing to try is to install the "normal" edge
kernel and try it out. The second is to edit your /etc/apt/sources.list
file and add a line there, exactly like the current one that says
"planetcore" but instead replacing "planetcore" with "planetedge". And
then install the newer edge kernel that's there...
