This is adding the additional cpufreatures aliases: alias: x86cpu:vendor:*:family:*:model:*:feature:*00E8* alias: x86cpu:vendor:*:family:*:model:*:feature:*0016* and since powernow-k8 used to load on 3.6-stable, it probably happened because the 0xe8 feature and since 3.7 moved it to acpi-cpufreq, this patch should actually fix it.
