I've done my best so far to solve my problems with information available but I've hit a rut and I'm hoping I can get help here.
I have a SuperMicro X8SIL-F motherboard with a WinBond W8367DHG sensor chip.
The CPU is an Intel Xeon X3440 running stock at 2.53GHz.
I am running UNRAID v4.7 which is based on Slackware kernel 2.6.32
This came with sensors v3.0.3 and libsensors v3.0.3.
I have tweaked my sensors3.conf based on comparable systems as well as the thresholds specified via the boards IPMI interface.
PROBLEM: Upon booting the sensors readout displays reasonable values and all the min/max values are as I set them. No ALARMs visible.
Within hours (minutes?) various min/max values change causing the reasonable voltage/rpm/temp to now be out of range... resulting in ALARMs being raised.
QUESTION: What is causing, say, the VBAT min value to suddenly change from my setting of +2.82V to 0V? Or the min RPM for HD FAN 2 to change from 400RPM to 0RPM?
Simply executing "sensors -s" again changes the values back and clears the ALARMs, but this is not feasible to do this multiple times per day after confirming the ALARMs are false.
On a slight aside, I am unable to set the div values on my fans and the associated /sys/class/hwmon4/device/fanX_div files are read-only.
As these values change causing ALARMs to be thrown in the sensors output, there is no related events in the IPMI sensor logs.
Any help appreciated!
Find below the relevant section from my sensors3.conf file.
