I agree. 3.8.x rt seems to be really really good for audio work, the 
best I have seen in a long time. I have run jack and other programs for 
days on end with no xruns (same hardware, same software, older kernels 
exhibited some occasional xruns).

Correct, I think just yesterday or the day before there were messages in 
the rt kernel mailing list indicating that a solution to the resume 
problem had been found. It is a known issue.

I would say the kernel is pretty stable other than the resume problem. I 
have to incorporate the resume patches or wait for a new rt release (I'm 
testing 3.8.10-rt6 but that does not include the resume patches - I may 
release today). Resume issues will probably have to wait till I get back 
from the Linux Audio Conference...

Thanks for the feedback!
