At -p4 I just get messages about the Jack watchdog timer timing out.
This is all getting pretty silly down that low. No reason I know of to
do it other then to test the limits of these new kernels.

Hi all,
OK, Last evening and this morning I have made good headway. It
appears that the main culprit was ACPI support, or some part of it.
With most of the ACPI stuff now disabled in the kernel build I am able
to run jack with no clients attached, as a root or user with the lsm
module modprobed, at p=8, n=2 for over 1 hour with no xruns. If my
calculations are correct this would be a latency of less than 0.5mS!
p=8??? good lord. I'd like to see you try that with any real apps :-)
I'm happy if I can get 128, would like to get down to 64 reliably...
