strange "sensors" readings



Hello !

At last, with Kernel 2.4.17 I got sensors to work.

But the results are a bit strange :

as99127f-i2c-1-2d
Adapter: SMBus Via Pro adapter at e800
Algorithm: Non-I2C SMBus adapter
VCore 1:   +1.77 V  (min =  +1.74 V, max =  +1.93 V)              
VCore 2:   +0.11 V  (min =  +1.74 V, max =  +1.93 V)       ALARM  
+3.3V:     +3.28 V  (min =  +3.13 V, max =  +3.45 V)              
+5V:       +4.84 V  (min =  +4.72 V, max =  +5.24 V)              
+12V:     +12.01 V  (min = +10.79 V, max = +13.19 V)              
-12V:     -12.08 V  (min = -10.73 V, max = -13.19 V)       ALARM  
-5V:       -4.76 V  (min =  -4.74 V, max =  -5.24 V)       ALARM  
fan1:        0 RPM  (min = 3000 RPM, div = 2)              ALARM  
temp1:       +41°C  (limit =  +60°C, hysteresis =  +50°C)        
temp2:     +47.0°C  (limit =  +67°C, hysteresis =  +60°C)        (beep)
temp3:    +112.2°C  (limit =  +60°C, hysteresis =  +50°C)        
vid:      +1.85 V
alarms:   Chassis intrusion detection                             
beep_enable:
          Sound alarm enabled

Read my ASUS A7V266 User's Manual back and forth, but could not figure
out what "VCore 2" could mean. I can't imagine the 0.11V to be wrong
since my machine works really fine :)

The -12V are swinging strongly. Here are the values, taken each 5
seconds:

markus@Eddie: > for i in `seq 120`; do sensors | awk '/-12V/ { print $2
}'; sleep 5; done | tee 12V-.log-14.15
-12.08
-13.83
-12.12
-13.83
-12.44
-13.03
-14.23

and so on... I dared to attach a tiny xfig that shows these horrible
values...-5V behave the same way. This does not look good. The positive
Voltages are solid and OK.

The worst is the Fan: Most of the time, there is a "0 RPM", but the fan
is working (i can SEE it ;) ). Sometimes, for a few readings there are
29xx RPM as it should be.

I compared the values to those I can see in the BIOS Dialogs. There was

Motherboard Temp: 41°C
CPU Voltage: 63°C

Fan: 2636 RPM

VCore: 1.77v
+3.3V: 3.28v
+5V:   4.83v
+12V: 11.97v

No other readings are supported in the BIOS.
So only the CPU Voltage differs a lot, but that may be OK. The Fan
reading is OK most of the time, only sometimes 0 - inverse to the
sensors output.

This behaviour makes the sensors tool quite unusable for me...


Is this known for my chipset or do I have some strange mainboard ?
Oh, BTW:
markus@Eddie: > cat /proc/cpuinfo 
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 4
model name      : AMD Athlon(tm) Processor
stepping        : 4
cpu MHz         : 1410.205
