I had the same problem. Make sure you've uncommented the SMP=1 line in
the Makefile (I assume you've got a uniprocessor machine, haven't you?)

I don't know of a way to do it on SMP right now. It has something to do
with spinlocks released where they shouldn't, resulting in an infinite
recursive loop.
