[PlanetCCRMA] f10/2.6.26-rt not working/ffado use

[Raphael Raccuia]

Great!!!
I stopped SELinux in config panel: system -> administration -> SELinux
management: State: disabled... 
And don't ask me why, raw1394 is now loaded at boot... 
jack now works perfectly with ffado. I tested shortly recording a single
stereo track in ardour at 64/3 @ 48000Hz: I compiled a sofware,
installed 60Mb packages, went on internet, checked mails: no xrun!!!
I'll keep working with ccrma and report after some times how it goes...
Tank's for your help!!!
cheers,
raf
