But adding these to /etc/rc.conf would save that manual bother: > performance_cpu_freq="HIGH" > economy_cpu_freq="HIGH" > since /etc/rc.d/power_profile is run on ACAD events anyway, at least > with the default /etc/devd.conf No, unfortunately that's not sufficient. I really have to decrease and increase the frequency. I think the reason is that the ACPI kernel code simply ignores setting the frequency to the same value. Stefan
