Hi James and OpenBMC community,
We have a sensor for HwmonTempSensor which doesn't have a valid reading
until the host is fully booted. Before it's becoming alive and useful, it's
getting disabled in code (
because of errors thrown up by the hwmon driver. Ideally, the thermal
control loop should kick the fan to fail safe mode until no more errors are
Any suggestions on how we should handle this kind of sensor properly?
