>Description:
Polling ipmi(4) reports a negative value for the Temp sensor reports negative values:
>From ipmitool:
[smcafee@xxxx ~]$ sudo ipmitool sdr list
Temp | -63 degrees C | cr
..
>From freeipmi:
[smcafee@xxxx ~]$ sudo ipmi-sensors
1: Temp (Temperature): -63.00 C (5.00/125.00): [At or Below (<=) Lower Critical Threshold]
..
We have not seen this in any of the other Poweredges (850/1850/1950/2850/2950) we've deployed.
Using remote lan-based IPMI polling (ipmitool -I lan) does not exhibit this problem.
Here's relevant the sysctl/dmesg output:
[smcafee@xxxx ~]$ sudo sysctl -a | grep -i ipmi
