I'm
running the Fast Track Pro with 64 Frames and 2 Periods (2,9msec),
and if I just use Ardour, I rarely get xruns. I'm running Kubuntu Gutsy,
so if I can provide any information on my configuration, go ahead and ask
:-)

I tried ubuntu studio yesterday and i must admit that it worked better
than the last fedora.
Actually with fedora 6 on my older laptop and the same card i had almost
no xruns with 2 periods and 64 frames.
Which kernel are you using ? Did you tweak the irq priorities ?
Flo
I didn't tweak the irq properties and I'm using the latest realtime-kernel
(linux-rt in the repositories), though the ati drivers still don't work with
it - I'd have never bought an ati if I had known that I would only be using
linux... Here's my output of cat /proc/interrupts:

I don't know what it means, but maybe there's some information for you in
there ;-) . If it's of any effect, I'm running a generic kernel right now and
the card's not connected, but the system is the same. There's
no /etc/init.d/rtirq on my system, so I can't provide that information...
