First, thank you for your fast and complete answer!

What I see here is that you don't have a LM78. I think the chip has been misdetected. You are supposed to have an IT87 as your main sensor chip (actually, a SiS950 which is compatible with the IT87) using the it87 driver. > > Would you accept to test my driver? > > It would be a pleasure.

The rest of the modules look OK. Did the new sensors-detect tell you to still use the lm78 module? This would need to be fixed. BTW, the complete output (using script for example) of sensors-detect would be very welcome. I'd like to see if it behaves as it should. > $ sensors > eeprom-i2c-0-50 > Adapter: SMBus Via Pro adapter at 0400 > Algorithm: Non-I2C SMBus adapter > Memory type: DDR SDRAM DIMM SPD > Memory size (MB): 512 Do you have a single memory chip on the system, or is the second one not detected? > it87-isa-0290 > Adapter: ISA adapter > Algorithm: ISA algorithm > VCore 1: +1.72 V (min = +1.42 V, max = +1.56 V) ALARM > VCore 2: +1.24 V (min = +2.40 V, max = +2.60 V) ALARM > +3.3V: +6.62 V (min = +3.12 V, max = +3.44 V) ALARM > +5V: +4.80 V (min = +4.72 V, max = +5.24 V) > +12V: +12.84 V (min = +11.36 V, max = +12.60 V) ALARM > -12V: -14.24 V (min = -12.63 V, max = -11.41 V) ALARM > -5V: -7.15 V (min = -5.28 V, max = -4.81 V) ALARM > Stdby: +5.04 V (min = +4.72 V, max = +5.24 V) > VBat: +0.00 V > fan1: 2848 RPM (min = 0 RPM, div = 2) > fan2: 0 RPM (min = 3000 RPM, div = 2) ALARM > fan3: 0 RPM (min = 3000 RPM, div = 2) ALARM > Temp1/MB: +54?C (min = +20?C, max = +40?C) > Temp2/CPU: +87?C (min = +25?C, max = +45?C) > Temp3: -55?C (min = +25?C, max = +45?C) This is far better than with lm78, isn't it? :) Some things would need tweaking though. +3.3V needs to be correcting as described in the /etc/sensors.conf file (this is a known problem). Fans 2 and 3 are probably not present and should be ignored. Temp3 is probably not used (-55 is a common value to mean "no diode connected") and should be ignored too (add ignore statements in config file). BTW, please note that the config file is *not* overwritten by lm_sensors installations, which in a way is great since it will keep your own changes, but on the other hand could make you miss updates we do on the default config file. > The CPU temp can't be right, I use a XP2100+ with a Spire WhisperRock > III cooler, which seems very adaquate. > In the BIOS the monitor tells me both CPU and MB reach about 54 > deg. C. The it87 module has a temp_type parameter that should help. Try temp_type=0x38 and see if it's any better. If not (it could say -55 as temp3) it may mean that these sensors are not used, and this would make sense because the LM83 that is supposed to be present on your motherboard is a 4-temperature sensor. > No problems making and installing Jean, so thanks for mentioning this > update and your work on the driver of course. You're welcome. Actually I need you more than you need me. The problem now is that the lm83 data doesn't show at all, while it is supposed to. Could you please: 1* Tell me what you see in /proc/bus/i2c* (file names and contents)? 2* Tell me what you see in /proc/dev/sensors/ (file names and contents)? 3* Recompile the whole lm_sensors2 package using the DEBUG option (see the main Makefile)? I added some debug prints that should show in you system logs. This would be more than useful for debugging. If you encounter any problem compiling/installing the CVS checkouts, please let me know. We plan to release 2.8.0 soon now. If you are used to IRC, you may meet me on #sensorstuff on Freenode (nick Khali). This may make the driver debugging faster :) Thanks a lot again. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
