Comments are welcome. See the cpufreq(4) man page: debug.cpufreq.lowest Lowest CPU frequency in MHz to offer to users. This setting is also accessible via a tunable with the same name. This can be used to disable very low levels that may be unusable on some sys- tems. I think this is what you want. Regards, -- Rui Paulo
