This made me somewhat puzzeled too until I tried the kernel desktop for
Suse to find out, that it delivers real good.
I have virtually the same results on the same machine. The only
difference is, that the desktop-kernel is not the same as solid if Jack
is set for very low latency (such as: lower than 5ms). For the
reall-world day to day work with big Ardour-projects, I cannot find any
difference regarding xruns.

Ubuntu works OK for me here but is indeed not as solid and powerful as
Suses desktop-kernel. At the other hand I tend to use it anyway. There
are more xruns but not too many (about 2-3/h under serious load), it is
quite stable and forgiving(not a single case of jackd crashed or frozen)
and the best: it is the most comfortable distro I ever had. Listening to
youtube-videos or using any sound-source imaginable while Ardour is up
and running whithout even the need to think about how this happens is
kind of nice methinks ;-)
