Apparently, the problem occurs while CPU1 is being disabled (or at least
the message is printed at that time), which is highly suspicious, because we
shouldn't be doing _anything_ ACPI-related at this point (the SCI should
have been disabled way earlier and the GPEs should have been disabled as well),
so I'm not really sure what's the source of the ACPI messages.
It _looks_ like we may be executing an AML method while CPU1 is disabled,
which would be kind of ... sick.
