[EDIT]It’s still super buggy. Managed to record some tracks, but then Jack suddenly got zombified and I got this error message: “cannot read result for request type 7 from server”. Plus something about Broken Pipe. So we’re not quite there yet…[/EDIT]

Yes! I finally got it to work. So now I must write it down…
There may be several steps missing here, I’ve been fiddling around for ages trying to get this one to work. Anyways, here goes:

  1. You need a Realtime Kernel. Yes, you do. Go here for instructions: https://wiki.ubuntu.com/RealTime/Feisty
  2. Of course, reboot after your new kernel is installed.
  3. In terminal sudo modprobe raw1394 (or add to modules for permanent fix)
  4. Also in terminal sudo chmod o+rw /dev/raw1394 this one has to be done each time you fire up the firebox..
  5. Launch qjackctl AS ROOT (then realtime ‘just works’)
  6. Setup jack. My setup is: XRealtime, Priority 75, Frames/Period 256, Sample Rate 48000, Periods/Buffer 2, Port Maximum 256, Timeout 500, Interface hw:0, Audio Duplex, Input Channels 10, Output channels 10, Input/output latency both 0, Start Delay 2. And yeah of course: driver freebob.
    I’m pretty sure I will tweak these settings later, but leave it like this for now,. it works:)
  7. Then launch Ardour as root. Start your session. And start recording!
