That points to a realtime kernel problem with (probably) timekeeping in
two core processors (ie: "time of day" is not perfectly synchronized
between the processors so that if jack migrates from one to another it
appears as there has been too much delay and things don't work as
intended). I have seen this happen in 2.6.23.x + rt14.

What happens if you boot dual core with the "idle=poll" kernel
parameter? (I assume this happens with 2.6.22.x).
