Well, we're trying to find where it's hanging, so we can't get something
really useful without hanging your PC, unless the message buffer survives
across reboot(some does). Roughly there are three places where the hang
can occur; probe, attach, and the idle hook, and we need to determine
where it is hanging. If you remove "ACPI_NAMESPACE" from debug.acpi.layer
and reboot without disabling "cpu" subsystem, do you see a few lines
containing "cpu", "CPU", or "Processor" on the console? If it does,
let me know them.
