  Hi all,
 I'm trying to set up my Phonic Helix Board 24 on Fedora 10. I've added
 the CCRMA repository but I'm *not* running a CCMRA kernel. I have just
 used this repository to install ffado and jack.
 [jonathan@poseidon ~]$ uname -r
 2.6.27.12-170.2.5.fc10.i686.PAE
 [jonathan@poseidon ~]$ rpm -q ffado
 ffado-2.0-0.6.rc1.fc10.ccrma.i386
 Starting jack gives the output below. Running as root gives exactly the
 same output. I've made sure that all users have read/write permissions
 on the firewire port (chmod a+rw /dev/fw*)
 I'm a fairly experienced Linux user but I know very little about audio
 on Linux. Can anyone shed any light on this? I had the same Phonic device
 working on Fedora 8 some time ago but that computer is now a distant memory...
 Any help will be gratefully accepted! 
The firewire stack that is built into the Fedora kernels is not
compatible with FFADO. The Fedora kernels have been broken for firewire
audio for a loooong time.
If you want to use FFADO you will have to boot into the Planet CCRMA rt
kernel which has been build with the old firewire stack (which probably
will have other problems - such is the current state of rt patch, oh
well).
The issue has nothing to do with the rt patch or running with -R, it is
just the wrong (newer) firewire stack.

 I use Gentoo and have just ordered a Focusrite Saffire.. Will either the gentoo
kernel or the rt patched gentoo kernel (from the pro-audio) overlay have these
issues?
