hi ,
I have installed lm-sensors with i2c, ipmi and bmcsensors modules but
the sensors command give me wrong values :

# sensors -s     --> no output ?
# sensors

my sensors-detect output :# sensors-detect 

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to
all
questions, unless you know what you're doing.

 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no): 
Probing for PCI bus adapters...
Use driver `i2c-piix4' for device 00:0f.0: ServerWorks CSB5 South Bridge
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Module `i2c-piix4' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
 i2c-dev is not loaded. Do you want to load it now? (YES/no): 
FATAL: Module i2c_dev not found.
 Loading failed, expect problems later on.

 We are now going to do the adapter probings. Some adapters may hang
halfway
 through; we can't really help that. Also, some chips will be double
detected;
 we choose the one with the highest confidence value in that case.
 If you found that the adapter hung after probing a certain address, you
can
 specify that address to remain unprobed. That often
 includes address 0x69 (clock chip).

Next adapter: IPMI adapter
Do you want to scan it? (YES/no/selectively): 

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan the ISA bus? (YES/no):

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

 Now follows a summary of the probes I have just done.
 Just press ENTER to continue: 

Driver `bmcsensors' (should be inserted):
  Detects correctly:
  * ISA bus address 0x0ca0 (Busdriver `i2c-isa')
    Chip `IPMI BMC KCS' (confidence: 4)


 I will now generate the commands needed to load the I2C modules.
 Sometimes, a chip is available both through the ISA bus and an I2C bus.
 ISA bus access is faster, but you need to load an additional driver
module
 for it. If you have the choice, do you want to use the ISA bus or the
 I2C/SMBus (ISA/smbus)? 

To make the sensors modules behave correctly, add these lines to
/etc/modules:

#----cut here----
# I2C adapter drivers
i2c-isa
# You must also install and load the IPMI modules
i2c-ipmi
# I2C chip drivers
bmcsensors
#----cut here----


well, I don't understand anything about theses sensors output values. Is
ther a problem with the chip module ?
what can I try to resolve it ?

thanks
