[Bug 234455] CPU frequency scaling fails for multiple cores

--- Comment #6 from Dave Green <dg at fastmail.co.uk> ---
CPU is 800 at boot either with or without powerd.

Temperature is always stable at 25 degrees.

I'll retry debug.acpi.disabled="thermal" but I don't recall it having any
effect for 11.2-RELEASE.

If I comment out the conditional in cf_set_method() at kern/kern_cpu.c:291 then
both sysctl and powerd can be used to adjust the frequency.

>            sc->curr_priority);
>        error = EPERM;
>        goto out;
>    }
