I have a problem with jack. I have a Edirol fa-101
firewire soundcard on
amd processer (2500+) with 512Mb RAM. If i have low frames/period setting
( 128) jack shots down after short time (2 - 20 sec or almost instantly if
I run a program; ardour or openoffice) or if I have a high frames/period
setting (1024) I get xruns.
I have tried almost every setting possible and tried changing nice values
on the firewire card and a lot of other stuff.
Changing nice-values will not help because:

radeon@pci:0000:01:05.0
...your firewire-controller shares its interrupt with the graphics card. That
will almost always make problems.
And using a pccard won't help you, as your pccard-slot shares that same
interrupt as well. Bummer.
It might be that your BIOS allows selecting interrupts for devices. Other then
that I fear you are completely out-of-luck with that laptop for firewire-audio.
My Firewire card:*
thomas@thomas-laptop:~$ lspci | grep Fire
00:0a.1 FireWire (IEEE 1394): Texas Instruments PCI4410 FireWire Controller
(rev 02)
I think that one should work (if it wasn't sharing the interrupt).
A side-note: There is a reason the ffado-README contains instructions what to
report in case of errors. Mostly a verbose log of jack. And the output of
ffado-diag...
Have fun,
Arnold
