But that wouldn't explain why restarting powerd helps ?

Hi,

A bit weird to try to give suggestions knowing how experienced you are in FreeBSD. But here we go,

1. What does the sysctl about cpu frequencies say. Does that value decrease too?
On my machine it is this:
# sysctl dev.cpu  | grep freq
dev.cpu.0.freq_levels: 1500/-1 600/-1
dev.cpu.0.freq: 1500

2. Does https://www.freshports.org/sysutils/powerdxx/ exhibit the same issue? To rule out if it is in the binary or in the kernel.

3. out-of-the-box: are your CPUs similar? So, do both have the same top frequency?

4. And powerd(8) mentions a -v option: "Verbose mode.  Messages about power changes will be printed to stdout and powerd will operate in the foreground."
Does that print anything useful?

Regards,
Ronald.
