Hello I've just build a 2.6.22.1 kernel and latest lm-sensors with coretemp driver coretemp.ko is driver loaded properly .... #cat /etc/modules i2c-i801 w83793 w83627hf coretemp #dmesg ... coretemp coretemp.0: Using undocumented features, absolute temperature might be wrong! coretemp coretemp.1: Using undocumented features, absolute temperature might be wrong! In my sensors.conf I've got this #Core0 chip "coretemp-isa-0000" label temp1 "Core0 Temp" # Core1 chip "coretemp-isa-0001" label temp1 "Core1 Temp" Unfortunately when I exectute #/usr/local/bin/sensors coretemp-isa-0000 Adapter: ISA adapter ERROR: Can't get temperature data! w83793-i2c-0-2f Can't get adapter name for bus 0 VCoreA: +1.32 V (min = +0.92 V, max = +1.49 V) VCoreB: +1.53 V (min = +0.92 V, max = +1.49 V) ALARM Vtt: +1.21 V (min = +1.08 V, max = +1.33 V) in3: +0.51 V (min = +0.38 V, max = +0.69 V) in4: +1.82 V (min = +1.62 V, max = +1.98 V) +3.3V: +3.38 V (min = +2.96 V, max = +3.63 V) +12V: +11.81 V (min = +10.75 V, max = +13.25 V) +5V: +5.00 V (min = +4.64 V, max = +5.65 V) 5VSB: +5.07 V (min = +4.64 V, max = +5.65 V) VBAT: +3.23 V (min = +2.99 V, max = +3.66 V) fan1: 11637 RPM (min = 712 RPM) fan2: 11440 RPM (min = 712 RPM) CPU1 Temp: +37.2 C (high = +60.0 C, hyst = +55.0 C) CPU2 Temp:-110.5 C (high = +60.0 C, hyst = +55.0 C) temp3: -128.0 C (high = +60.0 C, hyst = +55.0 C) temp4: -128.0 C (high = +60.0 C, hyst = +55.0 C) temp5: +39 C (high = +80 C, hyst = +75 C) coretemp-isa-0001 Adapter: ISA adapter ERROR: Can't get temperature data! More someone could explain me why I've got an ALARM on my VCoreB ? I've got a supermicro PDSMi+ motherboard Thanks for the help Regards
