Yes, I'm certain acpi_cpu_detach is not being called before
AcpiTerminate(). Can someone with some newbus knowledge explain this?
devinfo shows acpi_cpu0 as a child of acpi0 so its detach should be called
before acpi0's. Perhaps the fact that there is no DEVMETHOD for
acpi_detach means that its children never have their detach methods
called?
