--- Comment #12 from Kevin Bowling <kbowling@freebsd.org> ---
I am wondering if there is something electronically wrong or a negative
interaction with NC-SI (BMC).  You have a fair number of crc errors
dev.igb.0.mac_stats.crc_errs: 35330623 going on and supermicro gets things

In your watchdog, dumping dev.igb.0.reg_dump as well would be interesting.. it
wont dump by default if doing a higher level sysctl OID.

Try updating the BIOS and BMC
https://www.supermicro.com/en/products/motherboard/X10SRi-F and if you are
able, try FreeBSD 12-STABLE kernel.
