I've been monitoring CPU temperature on a few Dell SC1435s running CentOS4 via OpenIPMI and 'ipmitool sdr'. It's been working very nicely, but the upgrade to 4.5 not so long ago seems to have broken something: # ipmitool sdr type Temperature Temp | 01h | ns | 3.1 | Disabled Planar Temp | 04h | ok | 7.1 | 30 degrees C Temp Interface | 53h | ns | 7.1 | Disabled The disabled sensors above used to work fine, and there have been no config changes or bios upgrades or anything. All machines affected post 4.5. Any suggestions? Cheers, Gavin
