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



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

A quick google search showed this github project, which sheds some light (n=
ot
much).

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