This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --xf51pDQT1XH7PKhkR9tH2QuotsqAoBUNi Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi I just updated to FreeBSD 10.2, and I'm noticing that the CPU frequency levels available are much more limited compared to FreeBSD 10.1 on the same system. 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?
