OK. Back from work now (what a day!) and did a little more testing. Good news is (for me), I cannot make this "BIOS error", or whatever it was, reappear. Bad news is (for you developers), I cannot make the problem reappear for further debugging. I now get clean boots every time. The "unplug" did it. I have NOT uninstalled lm-sensors to see if I can reproduce the problem by starting back at the very beginning. I may attempt this at some time. I would still like to know what actually caused my problem, but I have a feeling that I'll never know. Now the sensors program is reporting good data, more or less. Below are the results from sensors and the results that BIOS reports during boot. Looks like the it8712 section gets the two fan speeds correct, and some of the voltages. Notable is that the it8712 reports the +3.3 as +6.5 whereas BIOS reads the +3.3 as +3.23 If you ignore the it8712 bad readings on -5 and -12 (these seem totally bogus), the rest of the it8712 voltage readings look good. The it8712 gets all the temperatures wrong however. Scroll down to the lm90 section and you'll see good readings for both the CPU and system temps. The eeprom section looks pretty useless to me, but the data it reports is correct. I didn't know you needed a "sensor" to tell you how much memory you have! ;-) The modules I currently have loaded related to lm-sensors are: it87 eeprom lm90 i2c_sensor i2c_isa i2c_nforce2 i2c_core Thanks! > ####################################### > What BIOS reports during POST (reboot): > --------------------------------------- > CPU Temp: 39 celcius > Sys Temp: 40 celcius > CPU Fan: 2721 rpm > Sys Fan: 4017 rpm > Vcore: 1.48v > CPU +5: 4.97v > CPU +3.3: 3.23v > CPU +12: 11.71v > 5V(SB): 4.86v > Battery: 3.02v > ####################################### > > david at familyroom:~$ sensors > it8712-isa-0290 > Adapter: ISA adapter > VCore 1: +1.49 V (min = +1.42 V, max = +1.57 V) > VCore 2: +1.49 V (min = +2.40 V, max = +2.61 V) ALARM > +3.3V: +6.50 V (min = +3.14 V, max = +3.46 V) ALARM > +5V: +4.95 V (min = +4.76 V, max = +5.24 V) > +12V: +11.71 V (min = +11.39 V, max = +12.61 V) > -12V: +1.60 V (min = -12.63 V, max = -11.41 V) ALARM > -5V: +3.96 V (min = -5.26 V, max = -4.77 V) ALARM > Stdby: +4.84 V (min = +4.76 V, max = +5.24 V) > VBat: +3.02 V > fan1: 2636 RPM (min = 0 RPM, div = 8) > fan2: 3924 RPM (min = 664 RPM, div = 8) > fan3: -1 RPM (min = 664 RPM, div = 8) > M/B Temp: +13?C (low = +15?C, high = +40?C) sensor = thermistor ALARM > CPU Temp: +127?C (low = +15?C, high = +45?C) sensor = thermistor > Temp3: +98?C (low = +15?C, high = +45?C) sensor = diode ALARM > > eeprom-i2c-0-50 > Adapter: SMBus nForce2 adapter at 4c00 > Memory type: DDR SDRAM DIMM > Memory size (MB): 1024 > > lm90-i2c-1-4c > Adapter: SMBus nForce2 adapter at 4c40 > M/B Temp: +39?C (low = +0?C, high = +127?C) > CPU Temp: +38.9?C (low = +0.0?C, high = +127.0?C) > M/B Crit: +127?C (hyst = +117?C) > CPU Crit: +127?C (hyst = +117?C) ======================================================================= Jean Delvare wrote: > Hi David, > > >>>How come that you use the lm90 driver while sensors-detect did not >>>suggest you should do so? >> >>sensors-detect >> did << suggest that I use lm90 on the first run. >>On the second run it apparently did not (possibly because the lm90 >>module was already loaded from the first run?)
