issues with powerd/freq_levels

[Daniel Braniss]

I am trying out PCengines latest apu2 boards, and I just noticed that with different Freebsd versions I get
different freq_levels, and so when idling, each box (have 5) has a different	freq/temperature value, ranging
from 125/69.1C, 600/59.0C to 75/56.0C

apu-4# sysctl dev.cpu.0.freq_levels
dev.cpu.0.freq_levels: 1000/980 800/807 600/609

dev.cpu.0.freq_levels: 1000/-1 875/-1 750/-1 625/-1 500/-1 375/-1 250/-1 125/-1

so, any ideas as to what is going on?
