Sorry, did not help: alex@t40:/proc/acpi/processor/CPU$ cat power active state: C2 default state: C1 bus master activity: ffffffff states: C1: promotion[C2] demotion[--] latency[000] usage[00000010] *C2: promotion[C3] demotion[C1] latency[001] usage[00164425] C3: promotion[--] demotion[C2] latency[085] usage[00000000]
