[lm-sensors] ASUS Kfn4-dre

[lm-sensors] ASUS Kfn4-dre

[Michael Weingartner]

Dear Ladies and Gentlemen,

I have a asus kfn4-dre serverboard. I use lm-sensors form ubuntu repositories.
With ubuntu 8.04 LTS. I had with full CPU load 55-60 degrees celsius.

I have done a distributionupgrade to 10.04 LTS and I use a backport kernel.

I have done a "sensors-detect" and now I have 40-50 degree celsius  
with k8temps CPU.

What do you think about this?

regards
mike

Nice, but all you are saying is that you use a kernel later than 2.6.32, but not exactly
which one. Not very helpful.

There were several changes in the driver over time to fix wrong temperature readings.
Which ones affect your kernel are impossible to say without knowing the exact kernel version.
