My observations are that FC8 and 2.6.24 -rt kernels are relatively
but NOT with compiz fusion/emerald. Compiz hangs my machine with or
an -rt kernel, 2.6.24 or 2.6.26 as soon as I start trying to do anything
all complex audio-wise.

I don't know if that's of any relevance to your problems but it seems to
to me consistently (so I don't use them any more).
