So the story is more interesting now... with SCHED_FIFO I'm seeing occational delays of about 60 sample frames (@44K) when there is very little other CPU activity. It still looks like a buffer underrun in that the audio data is contiguous on both sides of the delay, so I'm not dropping a buffer. When I load the CPU with another task doing a while(1) loop, the glitches go away. Hmmm....
You will probably need to run an -rt patched kernel to get acceptable performance from JACK. This also includes a cool latency tracing feature that will tell you what IRQ handler is using too much CPU time.
