Before I sent the first message in this thread, I added a bunch of
printks to this function.  They ended up mixed in with the panic, just
like the ACPI debugging messages.

I'm not sure what else I can do to "dig into" it.

My guess, and that's all it can be, is that the transition to ACPI mode
does something that causes the idle thread on the other processor to
crash.  Perhaps a spurious interrupt is being thrown, or an interrupt is
routed to the wrong processor.  (Is the behavior of a HLTed processor
that gets a misrouted interrupt different than that of a processor that
is polling?)

There certainly seems to be a timing sensitivity too.  Is there a kernel
mode sleep-like function that I could play with?

Thanks!
