What does cpufreq-info (package cpufrequtils) reports, especially, what governor is in use which cpu freq driver do you use? (The available drivers are listed in : /lib/modules/$(uname -r)/kernel/arch/x86/kernel/cpu/cpufreq/ I don't know which one is the best for your CPU, but google is your friend). > [..] How do I get it to ramp down its CPU Hz?

This is what the "ondemand" governor should do. > I've been through /etc/default fixing stuff there. I've fought with > /etc/cpufreqd.conf, to no result. "Restarting CPU Frequency daemon: > cpufreqd failed!" Ideas? I would expect this machine to be new > enough to handle cpufreq's latest abilities. I haven't used cpufreqd for a while. I think it isn't required. Have you tried to remove it, to return to pristine situation? Then you could use "cpufreq-set -g ondemand" to modify the cpufreq settings, live. Some extra hints * Make sure you run the latest (recommended) firmware. * Try using powertop to make sure that nothing prevents the CPU from sleeping.
