Comment 14 for bug 1907432

@juergh I've seen both the "bare" reboot: Power down followed by a long-ish delay and a kernel panic, and the repeated rcu_preempt messages that you posted in comment 10 under 1008. Neither appear to occur in 1007 so I'm guessing they might both be symptoms of the same issue? I'll see if I can hook up a serial console to a 400 this weekend and see if I can goad it into producing the kernel panic to get some legible output.

My rough observations are the rcu_preempt error occurs most of the time (I haven't seen the "bare" reboot: Power down error in a while), but I've definitely seen both under 1008 with the former the more common one.
