First, ACPI and APM simply do not play together, period. It's one or the
other, although ACPI does provide an APM emulator so that the APM
interface is still available to programs. But, if the BIOS on your
system supports APM, you might want to turn off ACPI and try running
with APM instead.
To turn APM on, DON'T rebuild your kernel. Just add the line:
apm_load="YES" to /boot/loader.conf and edit /boot/device.hints by adding:
You can switch back to ACPI by commenting out the lines.
Take a look at 'sysctl hx.acpi.thermal and see what values are actually
coming back from BIOS. The numbers are in unit of 1/10 degree Kelvin.
Finally, ACPI has had major changes since 5.1 and is MUCH better. I'd
suggest 5.2 as soon as it is released which should be very soon. (If you
feel a bit brave, you might go with the latest pre-release in
