Does that mean anything to you?

It looks like it is related to the multithreaded process-graph.

BTW if I choose "All available processors" the "Log" window says:
  Using 0 threads on 2 CPUs.
With "All but one processor" it's [mathematically] correct:
  Using 1 threads on 2 CPUs.

ardour3 does not hang and plays audio just fine in both cases!
That is svn-r7439. Do you need more info about the system?
