panic: spin lock sched lock held

Hi,

got this panic overnight. Machine was wedged solid and didn't enter ddb 
after the panic. I'll recompile with verbose diagnostics and see if it 
happens again. In the meantime, maybe the message will give someone a clue:

panic: spin lock sched lock held by 0xca462390 for > 5 seconds
cpuid = 0; lapic.id = 00000000
Debugger("panic")
