For my intel atom n2600, the lowest level available is 600Mhz, whereas with 10.1 it was 75Mhz. I've put my dmesg from boot at: http://www.caida.org/~mjl/atom-2600-dmesg.txt dev.cpu.0.cx_usage: 100.00% 0.00% 0.00% last 3645us dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_supported: C1/1/1 C2/2/20 C3/3/100 dev.cpu.0.freq_levels: 1600/2000 1400/1720 1200/1440 1000/1160 800/880 600/600 dev.cpu.0.freq: 600 dev.cpu.0.temperature: 34.0C dev.cpu.0.coretemp.throttle_log: 0 dev.cpu.0.coretemp.tjmax: 100.0C dev.cpu.0.coretemp.resolution: 1 dev.cpu.0.coretemp.delta: 65 dev.cpu.0.%parent: acpi0 dev.cpu.0.%pnpinfo: _HID=3Dnone _UID=3D0 dev.cpu.0.%location: handle=3D\_PR_.CPU0 dev.cpu.0.%driver: cpu dev.cpu.0.%desc: ACPI CPU Is there anything simple I can do to obtain the lower CPU frequency level= s?
