Description lethalwp 2010-03-21 19:37:59 UTC

In the bios of this asus p7f55d-v-evo mobo with corei5-661, cpuspeed options are enabled, but cpufreq doesn't register.

the i7z do show frequent mhz changes when load is applied, but i suppose it's motherboard controlled, and not cpufreq.

when booting the kernel with cpufreq.debug=7, dmesg shows:

~]$ dmesg | grep freq

this bugrequest can be closed,
in the asus bios, AITweak section, the option "ASUS/3rdParty UI Priority" has to be set to 3rdParty,

then acpi-cpufreq will load fine & cpuspeed governors will work
