I have a S2600CP motherboard, with two Xeon E2660 processors on it. It's in a non-intel chassis (a chenbro 1U case)
For some reason, the thermal margin sensors on the motherboard are not being recognized. This is leading to the BMC throwing an warning, and the fans being stuck at 100% all the time.
I've updated the BIOS and BMC to the latest version, as well as updated the FRU, and reprogrammed/validated the SDR configuration so the fans are set up properly, and they're correctly detected in the IPMI sensor readings dialog.
What can cause the thermal margin sensors to stop registering? All the thermal margin sensors are showing as "Unknown" with a reading of "Not Available".
This is doubly confusing as linux can see the temperature sensors in the CPU without issue, using the "coretemp-isa-0000" and "coretemp-isa-0001" interfaces.
