I found a thread in a FreeBSD mailing list which suggested adding the following to /boot/device.hints per the commit linked below:
Code: Select all
hint.acpi_throttle.0.disabled="1"
hint.p4tcc.0.disabled="1"
When I do that PowerD doesn't run at all. It spits out the following error message:
I suspect there is an ACPI issue. I fiddled with various power settings in the BIOS but the results were always the same.powerd: no cpufreq(4) support -- aborting: No such file or directory
Without PowerD and with various components plugged into the fitlet I still idle at just 6W so I can't complain.
