And I have ffado together with nvidia graphics (without sharing interrupts) 
working. So its not a software issue.

Now what?

Believe me: Sharing interrupts is still a bad problem in this century. At 
least when you have to interrupt-heavy devices like firewire and graphics share 
the IRQ.

And its not that re-assuring that the other operating system works: There you 
have a special driver that works around the hardware quirks. And if you look 
at your sound-devices documentation, they will tell you a long list of 
probably-not-working controllers and only a small list of working ones.

What it says, is that ffado (the bit of software you use to make jackd talk 
firewire) has an extensive README-file which explains what to do in case you 
need help or want to report a bug. Because most people (you too!) miss to get 
us all the information we devs need. And we feel that our spare-time is better 
spent hacking and fixing then telling people the same things over and over 
again. Thats why you really should read the README-files of apps/libraries.

Have fun,

Arnold
