What is Fervent?

That sounds like a great idea, I've even been tempted to install Windows on
the box just to see if the Windows software can handle the hardware
configuration. But that's not an ideal solution - since I would have to trash
the existing data on the machine to do it.

They are. I think. Using only one of the two cards works fine.

I think so. HDSPConf see's both of them. I can also capture from both. The
only problem is the XRUNs.

Yes, is that a problem?

I thought so too, but I'm really struggling with this. :(
I've been doing some further investigating...
I gather there are two places where XRUNs happen:
1) ALSA <--> JACK
2) JACK <--> JACK client
>From what I've been seeing when I play with the IRQ, JACK and qjackctl
priorites with chrt and the realtime-preempt kernel, I can cause the first
type by making the IRQ priority lower than JACK. jackd -v logs this as an
alsa XRUN. The second type is the problem I'm experiencing. Nothing shows in
the jackd -v output, but the client (qjackctl) sees XRUNs - usually a hundred
or so of them every few seconds.
