I compiled 2.6.29-rc8-rt4 yesterday and 2.6.29-rt1 today (my first self

compiled kernels). I happen to have the same interface and it seems to

work well here so far, everything seems to work and misbehaving

applications still produce xruns.
Thanks for the warning about irqbalance, I was about to try it..

(Is this the script by fernando lopez leczano or something else?)
If someone is interested I have a buildscript and config for arch linux.

It's probably not optimal, I don't know enough about kernels for that,

but it works.
Best regards

Philipp
