Thanks for that tipp - the could explain, why the box runs much better
with my workstation...

I gave it the treat, no errors occured...

Thats what I did, copied everything in the build-dir to that place in
/lib/modules (I upgraded to 2.6.22-15-rt beforehand).



jackd started promising:

 jackd --verbose -R -dfirewire -r44100 -p512 -n3 -v6 2> ffado-jack3.log

And seemed to run OK

but: alas:
qjackctl did not show any ports and crashed together with jackd 10
seconds after I started it

after I started jackd/ffado again, I tried ardour with some more success.

Ardour started and loaded a project, showed the ports of the firebox and
I could connect and play.

For about 3 minutes, then I witched to another virtual desktop (in
fluxbox) and ardour, jackd and ffado died immediately.

ffado-jack3.log and a new ffado-diagnosis-file
are NOT attached for they are to big you can find them here:

http://lapoc.de/archiv/ffado-jack3.log.tar.gz
http://lapoc.de/archiv/ffado-diag2.log.tar.gz


so there is some progress, but I am not there yet.
