still digging, but I'm getting stuck blocking on trying for a spinlock thats not
been initialized.  The workqueue at 0xffff8800003f5800 has been initialized, the
thread value is set and the lock init to 1 (unlocked on x86).  But the second
cwq for cpu1 is not initalized, thread is still NULL, and the lock value is 0
(locked).
