ipmi0: Watchdog set returned 0xc0 (releng_13)

Hi All,

    I updated a box from about a month ago, and noticed that the console
is full of

ipmi0: Watchdog set returned 0xc0

It fires every 30 seconds which is what I have the timer set to.  It
seems to be related to the ipmi watchdog as another box I have which
uses ichwd doesnt spew a similar message.

The only commit seems to be

Board is a Super Micro X11SCH-F. Bios 1.5 from 11/17/2020

My kernel is not that different from GENERIC. If I do a killall -9
watchdogd it reboots as expected.
