I'm not sure I follow what you are saying. I am seeing hw.setperf working only when acpi is disabled. This is not what I expected. Are you saying that hw.setperf is present without acpi, but when acpi is enabled it takes over that function but fails to make it work? In the dmesgs in which acpi is disabled, I have this line: cpu0: Enhanced SpeedStep 1200 MHz (860 mV): speeds: 1200, 1000, 800, 600, 400 MHz which is missing when I enable acpi. -- Mark
