Problem with sensors on linux 2.6.25
in [Kernel]

From: tockar on 4 May 2008 17:40 Hello, I've strange problem with Linux 2.6.25 and later (I've compiled 2.6.26-rc1 and I have same problem). In 'sensors' command result, I get ALARMs. Here's 'sensors' result on Linux 2.6.24: it87-isa-0290 Adapter: ISA adapter VCore 1: +1,71 V (min = +3,97 V, max = +1,95 V) VCore 2: +3,09 V (min = +3,82 V, max = +1,01 V) +3.3V: +3,07 V (min = +3,82 V, max = +3,06 V) +5V: +5,59 V (min = +4,27 V, max = +5,11 V) +12V: +13,31 V (min = +15,62 V, max = +7,74 V) -12V: -2,69 V (min = -0,61 V, max = +3,44 V) -5V: -9,14 V (min = +3,82 V, max = -2,62 V) Stdby: +0,00 V (min = +6,37 V, max = +5,03 V) VBat: +3,25 V fan1: 5152 RPM (min = 0 RPM, div = 2) fan2: 0 RPM (min = 0 RPM, div = 2) M/B Temp: +34,0�C (low = -7,0�C, high = -11,0�C) sensor = transistor CPU Temp: +33,0�C (low = -66,0�C, high = +127,0�C) sensor = transistor Temp3: +31,0�C (low = -33,0�C, high = -101,0�C) sensor = transistor Two minutes later, on Linux 2.6.25: it87-isa-0290 Adapter: ISA adapter VCore 1: +1,71 V (min = +3,97 V, max = +1,95 V) ALARM VCore 2: +3,09 V (min = +3,82 V, max = +1,01 V) ALARM +3.3V: +3,07 V (min = +3,82 V, max = +3,06 V) ALARM +5V: +5,59 V (min = +4,27 V, max = +5,11 V) ALARM +12V: +13,31 V (min = +15,62 V, max = +7,74 V) ALARM -12V: -2,69 V (min = -0,61 V, max = +3,44 V) ALARM -5V: -9,14 V (min = +3,82 V, max = -2,62 V) ALARM Stdby: +0,00 V (min = +6,37 V, max = +5,03 V) ALARM VBat: +3,25 V fan1: 5152 RPM (min = 0 RPM, div = 2) fan2: 0 RPM (min = 0 RPM, div = 2) M/B Temp: +35,0�C (low = -7,0�C, high = -11,0�C) sensor = transistor CPU Temp: +33,0�C (low = -66,0�C, high = +127,0�C) sensor = transistor Temp3: +32,0�C (low = -33,0�C, high = -101,0�C) sensor = transistor Results are almost identical, but I get those ALARMs. I've Pentium4 1,4Ghz processor, module for my mainboard is BLK_DEV_VIA82CXXX. Is that a bug?

The it87 driver in kernel 2.6.24 did not implement the standard alarm reporting, so sensors 3.x (which I guess you are using) couldn't report the alarms. This was fixed in 2.6.25, so now you see the alarms, but in fact they were already there before. All these alarms really mean is that you didn't bother fine-tuning your sensors3.conf file, or you did but you forgot to run "sensors -s" afterwards, so the low and high limits for each sensor aren't set properly. So, if you care about the alarms, you have to edit the configuration file. If you are lucky, we might have one for your board already, check at http://www.lm-sensors.org/wiki/Configurations and http://khali.linux-fr.org/devel/lm-sensors/ . But more likely you'll have to do the work by yourself. Note: I see that you are using a locale where a comma is used to display decimal numbers. There's a bug in libsensors which causes some statements of the configuration file to be parsed improperly in this case. This is fixed in SVN already, but until 3.0.2 is released and you upgrade to it, you should force your locale to C when running "sensors" or "sensors -s". -- Jean Delvare -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
