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? Can I
safely use Linux 2.6.25 or later?

No, it's not a bug. Yes, 2.6.25 can be safely used, do not worry.
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".
