Hi All,
I am having some issues with CPU scaling since updating to FreeBSD 9.0
I have in /etc/rc.conf
But when I do
I get an output as follows:-
Do I need to kldload anything?
(The processor is a P4)
Also, do I still need to do the C-state stuff?
Any help would be appreciated.

Any help would be appreciated.
