You must have dev.cpu.0.freq and so on. What kind of processor do you have? Does it support "powernow", "cool'n'quiet" or similar features? Also, make sure that you have "device cpufreq" in your kernel configuration. If you don't have it, try to load the module: kldload cpufreq Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
