Description heas 2022-04-27 23:25:47 UTC 
12.2-RELEASE-p15

I have had a few panics in the last few months, but I now have a large enough dumpdev.  Thus, I do not know if those were the same traceback & the host has been kept up-to-date with 12-RELEASE over this period.  I do not expect a high volume of v6 traffic to reach this host.

This is a non-debug kernel.  I'm happy to switch to one or collect other information.
