[lm-sensors] W83792D & Overtemperature LED on Supermicro

[ericb@aspsys.com (Eric J. Bowersox)]

Gentlemen, thank you for your responses.  Unfortunately, none of them
seem to have made a difference.

I set all unused "fan" channels to a minimum RPM of 0 and all three
temperature channels to a high of 70 and hysteresis of 60 (highest
actual reading of the three was 54).  Still blinking.

Changed that line, tried the new module.  Still blinking.

Tried that too.  Still blinking.

FYI, I can confirm that, at system reset time, the light is NOT blinking, and
that it is the action of loading the w83972d driver that causes the light to
start blinking (i.e. "modprobe w83792d" and blinks happen right then).

These dumps were taken with the driver with both patches loaded.  Before:

Any more ideas?  Our production engineer is happy for any assistance
you may have to offer in this matter.
