In IPMI site, why CPU1 and CPU2 temperatures are reading "Not Present!". I can see this under the "Sensor Readings" page. There are other sensors that show as "not present", but the CPU1 and CPU2 are the only two that have a red indicator next to them, and there are also entries for CPU1 Temp and CPU2 Temp in the event log saying "Overheat - Asserted", and "Overheat- Deasserted" quite often.
