Hi,

Welcome on board ;-)

The kernel is a normal preempt. As others have stated you need "PREEMPT RT"
to appear. Just so you know, I had tested building a JACK ipk and managed
to install it on an emulated phone a while back. I know some changed where
made by Paul to JACK's autotools stuff WRT code optimization for this
purpose.

Jack did run although I haven't been testing it deeply... I doubt the beast
is powerful enough to run fluidsynth.

Now, if you or others are interested, join #openmoko-devel on freenode.
we're working on a "Stable Hybrid Realease" here. It's good fun, and I'm
guessing that even if JACK is not what is used by the phone, all audio
hands are welcome. I got myself on the migration of the dialer to the new
dbus interface...

Cheers !
