After studying the ACPI, I realized that acpi_shutdown_final() doesn't get registered to "shutdown_final" event due to the fact /dev/acpi is missing. Therefore, the acpi_shutdown_final() doesn't executed when shutdown.

I'm not sure why the /dev/acpi is not getting created by devfs. Appreciate if could give your ideas.
