Did you try with higher latencies?
As long as you don't need to do software-monitoring, you don't need low-
latency for recording. It actually becomes safer to use higher latencies fo=
recording as the hd has more time to store and read the data.

Probably that is the reason. If ardour shows flashing VU-meters, your gui w=
update very often and generate lots of interrupts. This is guaranteed to=20
interfere with the fw-card.
While it is definitely worth trying to use the free driver (and the only=20
possibility to get support from kernel-devs and near-kernel-devs), I don't=
think this will improve your situation. I have the feeling that if you can'=
change the interrupt of either the graphics card or the pcmcia-slot, you ar=
out of luck. :-(
What is the exact model of your internal ricoh fw-controller? ("lspci -nn |
grep Fire" or add your line to http://subversion.ffado.org/wiki/HostControl=
