While I have some machines where I track stable/14 (for now), stable/15,
and head -- daily -- and the laptops use a kernel with ipfw compiled in,
I have not encountered issues with head since 17 December
(main-n282567-7a83fedc116d -> main-n282596-405188aeac54).  The most
recent build was:

FreeBSD 16.0-CURRENT #7 main-n282707-4f184fd35d81: Thu Dec 25 12:56:01 UTC 2025     root@g1-120.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/CANARY amd64 1600007 1600007

That said, those machines don't run jails.  They do use UFS file systems
on SSDs, though.

Peace,
david
