We've got a winner! 2.6.29-rt1

I've just succeeded with a few tests: jackd realtime (64fpp with a USB
UA25) recording/playing Audio and MIDI with qtractor & qsynth and I
played a 32 channel ardour session - no xrun in sight!

I know this is old news since 64studio already ships a 2.6.29
pre-release - However, I run a debian squeeze/sid and
2.6.29-release-candidates were causing an OOPS on this system.

As it turned out it was caused by "irqbalance"! It took me quite a while
to track down that the rt kernel is no longer compatible with irqbalance
(it works fine with 2.6.24-rt).

Here's a debian package built for core2:

and the corresponding .config file:
http://rg42.org/_media/wiki/kernel/config-2.6.29-rt1.txt

kudos to the rt-linux devs.
have fun,
robin
