Hi all!
Sometime ago I remember that my router scaled down CPU freq to 200Mhz.
Recently I've checked and there are only two freq levels:
freq_levels: 1867/135000 1596/89602 and it stays at 1596Mhz.
I need it to scale down to 200Mhz to conserve power - its a home server with low load. Also there aren't C2, C3 states.
I was on 10.2, upgraded to 10.3 without improvement.
The system is: HP Compaq dc7700 Small Form Factor, Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz
Some suggestions?
