If so then you will need to run 8.04 Hardy for the foreseeable future,
which isn't so bad. IMO Ubuntu Studio on Hardy is pretty swell. But,
if you're dead keen to move forward then it might have to be Intrepid
with the generic kernel...for a while. Which is what I plan to do.

As I indicated, Intrepid Alpha 6 is quite stable using the latest
generic kernel -- actually with applied patches it's now very stable
IMO and probably very close to being a BETA version -- but the same
8.10 apps on the latest develoment rt kernel are still prone to abrupt
app aborts and outright system crashing. (i.e. lobotomizing my AMD64
box 4-6 times a day). And I'm not even talking about freezes in Ubuntu
Studio apps. It'll will be in the middle of something in Firefox or
Nautilus or Open Office and suddenly flatline. :-(

It took me a few hours before the first blowup occurred. :-) By
contrast nothing is crashing my AMD64 system using 810 with the
generic kernel.

I ran the current rt kernel that ships with Hardy Ubuntu Studio
2.2.19), and a mix of the 8.10 apps. That combo seems to be fairly
stable, but I've only looked at a few audio apps that were of interest
to me. I didn't dig into any video apps, and didn't spend any time on
MIDI, or do any audio that would need very low latency. So take a big
pinch of salt with my saying that the current Ubuntu Studio rt kernel
might work for you with some of the Intrepid apps until the issues of
Intrepid and the 2.2.27x rt kernel get resolved.

Good luck to you. The way forward for Ubuntu Studio on Intrepid looks
to be quite an adventure! :-)
