[nSLUG] New Firewire Stack / ffado problems

Is anyone using the new firewire stack for audio / video? I'm trying
to run jack with an external fw device and it looks like a permissions
problem, but I'm not sure that it is:

Run as root or normal user I get the same result:

[root at caladan ~]# jackd -P70 -dfirewire  -p128 -n2
jackd 0.121.3

crc_itu_t               1363  1 firewire_core

and changing device permissions does not help.

I'm running 64bit Arch, and went as far as compiling latest libffado
svn, with the same result.

Any ideas?
