Temperature monitoring with OpenIPMI on Poweredge x9xx

[Olivier BONHOMME]

Hello,

I am writing on this list because I have a problem about monitoring CPU 
temperature On PowerEdge x9xx based on Core 2 Duo architecture.

I am using OpenIPMI 2.0.6-1 version downloaded from official Fedora Core 
6 repository.

When I want to check the CPU Temperature, ipmitool returns to me 
negative temperatures as follows :

Sensor ID              : Temp (0x1)
 Entity ID             : 3.1 (Processor)
 Sensor Type (Analog)  : Temperature
 Sensor Reading        : -53 (+/- 1) degrees C
 Status                : ok
 Nominal Reading       : 50.000
 Normal Minimum        : 11.000
 Normal Maximum        : 69.000
 Positive Hysteresis   : -127.000
 Negative Hysteresis   : -127.000
 Minimum sensor range  : Unspecified
 Maximum sensor range  : Unspecified
 Event Message Control : Per-threshold
 Readable Thresholds   :
 Settable Thresholds   : unc ucr
 Threshold Read Mask   : unc ucr
 Event Status          : Event Messages Disabled

 Entity ID             : 3.2 (Processor)

 Status                : ok
 Nominal Reading       : 50.000

 Negative Hysteresis   : -127.000

 Maximum sensor range  : Unspecified

Does anybody know if there is somewhere a way (patch, OpenIPMI 
customized by dell) in order to get the correct value for the CPU 
temperature ?

Thank you four your answers
