Why are you running a SMP kernel on a UP machine? One solution would be to run the UP kernel then you won't have any spinlocks :) I don't know of any SMP PowerStacks if there are any.
The actual cause of the bug you're seeing was p->processor being set badly in the fork code. It's fixed in the latest vger and Alan has a patch for it now.
