powerd (9.0-RELEASE)

Hi All,

I am having some issues with CPU scaling since updating to FreeBSD 9.0

I have in /etc/rc.conf
Code:
powerd_enable="YES"

But when I do
Code:
# powerd -v
I get an output as follows:-

Code:
blue# powerd -v
powerd: using APM for AC line status
powerd: error reading current CPU frequency: Device not configured
powerd: error reading current CPU frequency: Device not configured
CPU frequency is below user-defined minimum; changing frequency to 900 MHz
powerd: error setting CPU freq 900: Device not configured
powerd: error reading current CPU frequency: Device not configured
powerd: error reading current CPU frequency: Device not configured
powerd: error reading current CPU frequency: Device not configured

Do I need to kldload anything?
(The processor is a P4)

Also, do I still need to do the C-state stuff?
Code:
# sysctl dev.cpu.0.cx_lowest=C2
# sysctl dev.cpu.1.cx_lowest=C3

Any help would be appreciated.
 
I know on my server I fought for a few days trying to figure out why it was running strangely. I ended up commenting out the following in my sysctl.conf file:

Code:
dev.cpu.0.cx_lowest=C3
dev.cpu.1.cx_lowest=C3

I don't think I ever saw an explanation about it. I meant to follow up.
