[lm-sensors] Negative Values on many Systems

[lm-sensors] Negative Values on many Systems

[Anian Wurzenberger]

Hi List-Members,
I´m installing lm_sensors on some of our systems right now. On two of 
them I get a degree-value of -48,0°C respectively -48,5°C. Changing of 
the sensor-types doesn´t seem to help.
I supoose this means that the sensor-ports just aren´t in use, am I 
right? (I´m just asking because I seem to be missing the CPU-temp, or 
it´s just very low (31°C on an Intel 1800, 32°C on Intel 3000) ).

Thank you guys
Anian W.

Anian,

Some more details would be really helpful. It's impossible to answer
"It doesn't work, what's wrong?" kind of questions.

What kernel? What system/motherboard/hwmon chip? What version of
sensors? Logs? Ouputs?

Hi,
this is what I get on one system (Fedora5, kernel 2.6.15-1.2054 in this
case, but we use different versions of Fedora on other systems with the
same/similar problem) with sensors version 2.9.2 with libsensors version
2.9.2. (unfortunately I can´t find out what kind of board it is right
now (can´t reboot or take it out of the rack), but it´s some server
board with an Intel chipset):
 
w83627hf-isa-0290
Adapter: ISA adapter
[...]
temp1:       +32 °C  (high =   +50°C, hyst =   +45°C)   sensor =
thermistor   
temp2:     -48.0 °C  (high =   +85°C, hyst =   +80°C)   sensor =
thermistor   
temp3:     +29.0 °C  (high =   +85°C, hyst =   +80°C)   sensor =
thermistor
[...]
 
Changing the sensor-types brings different values, but no useful ones.
Also, the value doesn´t change over time, I always get -48.0 °C with the
thermistor setting.
If sensors logs into /var/log/messages, then there´s no entry.
I would have posted more info in the first post, but I thought (and
still think) this is a case of "no sensor attached", just wanted to make
sure.
 
Thanks
Anian

Yes, that's it.  Some other notes:

1) Use the 'ignore' statement in sensors.conf to hide temp2.

2) In theory, the BIOS should set the correct sensor type.  You shouldn't need
to change it.

3) You can run a CPU intensive process and watch for the other two temps to
rise.  The one that rises faster is probably the CPU.
