lm_sensors - sensors-detect

[AS]

On my Dell Laptop (Intel T8100 / ICH8 / 2.6.38.8-pclos3.pae) I'm used to have a gkrellm monitor including CPU temps, my system is actually fully updated and working.

However, while playing with the new kde-2011-06, kde-minime-2011-07 (an to some extent with the 64 bit test version), I noticed that the CPU temp sensors were not available, on the same laptop of course.

Installed lm_sensors package, and ran sensors-detect, nothing was found. After some comparison, found that the CPU temp sensors are available when the module coretemp is loaded, and that that modules is defined to be loaded in /etc/sysconfig/lm_sensors:

# Generated by sensors-detect on Sat Feb 19 20:34:42 2011
# This file is sourced by /etc/init.d/lm_sensors and defines the modules to
# be loaded/unloaded.
#
# The format of this file is a shell script that simply defines variables:
# HWMON_MODULES for hardware monitoring driver modules, and optionally
# BUS_MODULES for any required bus driver module (for example for I2C or SPI).

HWMON_MODULES="coretemp"

# For compatibility reasons, modules are also listed individually as variables
#    MODULE_0, MODULE_1, MODULE_2, etc.
# You should use BUS_MODULES and HWMON_MODULES instead if possible.

MODULE_0=coretemp

I have then removed the file /etc/sysconfig/lm_sensors and re-runned sensors-detect, which didn't find any sensors:

....
Sorry, no sensors were detected.
This is relatively common on laptops, where thermal management is
handled by ACPI rather than the OS.

Anyone can confirm similar results ?

i can ... and you have to use acpitemp to get temp of processor

May be I'm missing something here ... I actually do have temp sensors, as described in previous post.
I do not find sensors upon new installation of kde-2011-06/minime-2011-07/PCLinuxOS64-test01.

The question is: "is sensors-detect actually broken ?"

if I do not load coretemp module, I do not have any CPU temp sensors available in gkrellm, only the GPU temp sensor.

I have the same problem on my laptop. Anyone knows more about this?

Maybe is the sensor chip (SMBus) not detected?

I have it on my laptop too (even when running the stock kernel), but as I only noticed the problem on 64-bit I assumed it was just because it's not finalised yet. If the newer 32-bit ISOs give the same result, there's a need to see what's changed.

I have a different problem ........  seems some parts of my PC are hard frozen - according to this output ...

.......  and the 5V line reading  2.9V     Probably is referring to 3V line ......

Essentially I cannot depend on the figures at all .......

tried it on my dell lappy and no sensors found.... yet gkrellm is showing two temps ?

which Dell model ?

from http://www.lm-sensors.org/wiki/Devices

Dell    Inspiron, Latitude, Precision, Vostro
driver: i8k
interface: BIOS    
supported since kernel: 3.0 or  standalone driver    (2011-05-27)
The driver is old, but it did not implement the standard hwmon interface until kernel 3.0. Please test the standalone driver and report. The monitoring part should be working fine, but the fan speed control part is still experimental.

mine too is a Dell

older latitude D620
