I think I've heard rumors of some BIOS's only supporting APM in real mode;
and also rumors that this was the reason for Windows sometimes shutting
down so slowly - it has to do a switch to real mode to make the APM
poweroff calls. Feel free to correct me if I've heard wrong :)
I *know* APM in 4.2-stable did not and does not work on my laptop (some
kind of Asus). The ACPI from -current worked fine once when I tested it,
but I had to go back to -stable for various reasons, and now I've already
gotten used to turning it off by hand after the shutdown command.
(Note: no bad feelings here, if it's the BIOS's fault, there's nothing
the FreeBSD developers can do about it; and no, I would not want anyone
to add mode switching code to FreeBSD solely for shutdown purposes :)
G'luck,
Peter
