[Solved] lm-sensors fan speeds and voltage.

After installing lm-sensors and running sensors-detect I have the following readings from sensors;

~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +42.0°C  (crit = +80.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +47.0°C  (high = +78.0°C, crit = +100.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +42.0°C  (high = +78.0°C, crit = +100.0°C)

I am sure in the recent past I was able to retrieve fan speed and voltage readings from this machine;

|Abit FP-IN9 SLI | Intel(R) Core(TM)2 Duo CPU E8200@2.66GHz | GeForce 9800 GT |

I suspect this is something that I am doing wrong (or is it a kernel issue??) as I have the same problem on a similar machine running Ubuntu 10.04.

Any ideas appreciated.

Re: [Solved] lm-sensors fan speeds and voltage.

Looks to me as though you didn't modprobe your motherboard's kernel module
Probably it87 - sensors detect should have told you which one.

EDIT: did you: add the acpi_enforce_resources=lax to your grub menu.lst?  See this wiki article.

Re: [Solved] lm-sensors fan speeds and voltage.

add stuff as graysky has suggested. I did so this morning Plus u need to add sensord in ur DAEMONS array in /etc/rc.conf.

I have one question though, when I run sensors-detect, in the end it tells us to copy prog/init/lm_sensors.init to /etc/rc.d/lm_sensors file. Where do I find this lm_sensors.init file?

Thanks for your input graysky-you might well be right!

Hi graysky,
You were spot on!
I followed the instructions in the wiki article to add

acpi_enforce_resources=lax

to /boot/grub/menu.lst

Reboot...

Voila!
