Hi Franco, The fact that you're getting some negative degrees in ipmitool means something is probably wrong with the IPMI firmware on your mobo. Something is definitely not right.
The first thing to try is to run ipmi-sensors w/ --bridge-sensors. It's possible the sensors aren't on the main IPMI bus, so they need to be bridged to other devices on the motherboard. As a second shot, this seems similar to a bug I saw on a HP machine. Could you try running with the "-W discretereading" flag w/ ipmi-sensors. Maybe that will fix the problem. It would also be interesting to compare FreeIPMI's ipmi-sensors output to ipmitool's 'sensor list' output (ipmitool's assumptions are different in that code path). If that doesn't help, could you send me the --debug output from ipmi-sensors. I'd have to look into detail what is actually going on on this motherboard. As a side note, you may be interested in the --entity-sensor-names option for ipmi-sensors. It may make your output better for your motherboard.
