This does not quite work.

I don't get the panic() anymore, but now I have solve the hanging. :)

Perhaps only need_resched() needs to be spinlocked. I am not sure, I am not a SMP guru.

That looks correct, need_resched() needs sched_lock.

I'm currently looking to see if forward_roundrobin() does as well.
