Sorry, this is the hotplug stuff which surprised me, but is unrelated to any deadlock (unless it's printk'ing at a bad time, which I doubt). Thought it was an arch complaint about trying to wake already-woken cpus.

Seems to be timing related, printk's in init/main.c made it go away. ISTR hearing something about hotplug merge troubles, I'll investigate that thread and report results with the fixes posted there.
