Ah.. I have just tried 2.4.23 with the low latency patch again.. and I
agree.. Jack is much more stable. I am not sure I was getting as many
xruns as you, but in 2.4.23 I am getting absolutely none, even being
quite rough with opening and closing things.. Even running kernel
compile in the background!

This paired with the kernel panics I was getting on shutdown makes me
think that 2.6.x is not quite ready for audio yet.
