the shutdown code is new and might be wrong. worked here.
I'll double check.

using "echo reboot $kernel>/dev/reboot" with mp irqs,
i'm getting one of three conditions
1. a normal and very quick start of the new kernel.
(one odd bit: lapicerror: 0x00000000. i assume that's
the unanswered ipi.)
2. a reset and not a reboot
3. a hang right after after the LAPIC: ... line.
i can get all three conditions on my little atom
machine. other machines would rather not boot
the new kernel, they either reset or hang.
so the question is, is this a known problem or is
this a hardware or operator error?
