(I post here and not on "mobile computing" because it may be an issue not only with laptops and notebooks, etc.)
The problem is FreeBSD's power policy which actually does NOT limit cpu power: neither powerd nor power profiles work properly.
For example, I have the following in my configs:
rc.conf:
loader.rc:
As you see, powerd is configured to minimal frequency available on my cpu (without throttling), and lowest possible power states chosen (C3). But instead CPU burns like a hell-fire when it is under load (even on battery) - that is I think main source of all my powersaving-related problems.
Anyone else encountered this? Maybe something in the drivers, because I'm unable to find any power (not frequency) related settings
