Hello,
I just moved my Freenas over to a new box that has an AMD processor that supports its Cool 'n Quiet power saving scheme, which is turned on in the BIOS by default. I'm running Freenas 8.04 x64 with powerd enabled and first time I booted up the new box I started receiving an error message every few seconds - "hwpstate0: set freq failed, err 6". After a little web research, I found that if I disable Cool 'n Quiet in the BIOS the error messages stopped.
On the web I found articles saying that FreeBSD, starting with version 6.0, does support Cool 'n Quiet, so I'm guessing that whatever is needed for that isn't implemented in Freenas' BSD? Any FreeBSD experts out there know how to get this working in Freenas? On the other hand, what's different between what powerd and Cool 'n Quiet do? As I understand it, both automatically adjust the CPU's frequency based on its load, so maybe leaving Cool 'n Quiet disabled doesn't waste energy?
Thanks for your help.
