Load it and see what it reports. Weirdly enough, trying to load "coretemp" on the new hardware gives me a "No such device" error ... Like Jean mentioned, I am running a rather old version, due to having old packages and all their baggage. I took the newest version from http://dl.lm- sensors.org/lm-sensors/files/sensors-detect and reran it on all the systems I have access to. sensors-detect output: Driver `coretemp': * Chip `Intel digital thermal sensor' (confidence: 9) Driver `f71882fg': * ISA bus, address 0x295 Chip `Fintek F71808A Super IO Sensors' (confidence: 9) #----cut here---- # Chip drivers modprobe coretemp modprobe f71882fg /usr/bin/sensors -s #----cut here---- >> Not temp2 and temp3 though.

Sensors-detect tells me to load coretemp, using the latest version of sensors-detect from the site wants to also me to load the f71882fg driver. That doesn't work out with a 'No such device' error. >> >What is your kernel version, and what exactly does sensors-detect report ? I am on debian sqeeze, running 2.6.32-5-686 sensors-detect gives me this: Driver `coretemp': * Chip `Intel digital thermal sensor' (confidence: 9) Driver `lm78': * ISA bus, address 0x290 Chip `National Semiconductor LM78' (confidence: 6) Driver `f71882fg': * ISA bus, address 0x295 Chip `Fintek F71869F/E Super IO Sensors' (confidence: 9) #----cut here---- # Chip drivers modprobe coretemp modprobe f71882fg modprobe lm78 /usr/bin/sensors -s #----cut here---- coretemp is loadable, but f71882fg gives me this: ~/detect# modprobe --first-time -v f71882fg insmod /lib/modules/2.6.32-5-686/kernel/drivers/hwmon/f71882fg.ko FATAL: Error inserting f71882fg (/lib/modules/2.6.32-5-686/kernel/drivers/hwmon/f71882fg.ko): No such device >If I interpret the information I find on the web correctly, the board might >be MI812 or MI810 from iBT.

Trying to load w83627ehf gives me the same "No such device" error. >> Acpitz-virtual-0 >> Adapter: Virtual device >> Temp1: +30.0°C (crit = +100.0°C) >> Coretemp-iso-0000 >> Core 0: +30.0°C (crit = +90.0°C) >> >The CPU is Atom N270, so the reported critical core temperature is correct. >CPU temperature measurements are highly inaccurate that far below the maximum >temperature, so the reported value is as good as it gets.

I need to find out if the system had been used in the wrong environments, which might have lead to the demise of the hardware. How accurate are we talking here? I just want to set a threshold to watch over, maybe setting it to ~50 degrees as a first stepping stone. >> Both are no realistic values. Temp1 never changes. The Core 0 temperature seems too low (both systems feel roughly the same to the touch from the outside), it does change if I put a ventilator beside it. >> I feel quite out of my field in this, could someone give me a pointer or two what might be going on or where I could read up to understand this weird situation? > >Not really weird at all, but quite common. This makes me feel at least a tiny bit better. :) _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
