lm-sensors with k10temp not detected

Hi, I am new to gentoo and I am having a problem with lm-sensors. I have an AMD phenom II x4 905e and the related kernel module k10temp loaded. sensors-detect does not detect this for some odd reason. I am not really sure what to do, I have spent all day trying to figure this out. Here is some information that might be useful:

Moved from "Other Things Gentoo" to "Kernel & Hardware", as OTG tends to be fairly low traffic, and technically we can get away with having this here

(I don't really have any ideas, i have a k10 but havent tried anything with lm-sensors)

I'm on the wrong box just now, but AFAIR on my AMD Phenom box with a similar CPU, the kernel disables the temperature sensor because it's known to be unreliable on this chip series. Check your dmesg output and I think you'll find a message disabling it. Net of this is that you let BIOS manage the CPU temperature; you can't do it from linux.

Supposedly, you can load the k10temp module with the 'force=1' option, and override the disabling of the monitoring.

You'll then need to make your own judgment if the values are accurate (or at least usable).

Yep, that was the problem.

Sorry to bump this with a new post. It seems that it still might not be working properly. I am only getting one temperature from k10temp and it isn't cpu temperature.
sensors-detect still says:

I am seeing this too with an AM3 CPU on an AM2 socket. Does anybody know what would be the syntax to add this to the kernel commandline? All examples I've found so far mention modprobe and its config files, but I have k10temp built-in.

njsg,

You can pass module parameters to a built in module on the kernel command line.
The syntax is <module_name>.<param_name>=<value>
