FWIW I've tried Intrepid with the 2.2.26 rt for AMD64 for about 10
days. In one word "don't". There's a laundry-list of things that cause
the system to lock up and go braindead -- many of them video and audio
driver related. But many apps appear to work on the generic kernel
(performance issues aside). And many of them appear to work in the
latest (Intrepid alpha 6) versions using the 2.2.19 rt kernel that is
available for Hardy.

I have to agree with Cory that for now Ubuntu Studio users should
stick with Hardy because the 2.2.26 rt kernel is not ready to go as
part of Intrepid, let alone as part of Ubuntu Studio Intrepid. That
may change in the next 30 days, but I suggest letting Cory et al pull
their hair out and swear at their computers dealing with the problems
of 2.2.26 rt. YMMV.
