--- Comment #1 from georg.lastname at web.de ---
Regarding the warning: Pm2ControlBlock being zero just means that this register
block is not supported by the firmware. It's optional anyways.



Regarding the errors: The firmware is looking for a method called ALIB on the
system bus (_SB). It is hard to find information about what this method does.
Not sure if it is documented somewhere (surely not in the acpi specification).

A quick google search showed this github project, which sheds some light (not
much).

Either way, I don't think FreeBSD can do anything about it (it's a firmware
issue).
