There were changes to bpf. Maybe try those.

Onderwerp: Panic during boot on assertion in ipfw strtup
As of current as of Dec 16 21:22:39 UTC 2025 m system panics when starting
ipfw. was not happening on 2f29d0f3e6d2 on Saturday Dec 13. I tried to get a
dump, but the system did an immediate reboot when I tried 'panic'. Here is the
panic output:
Dec 19 07:12:30 ptavv kernel: ipfw2 (+ipv6) initialized, divert loadable, nat
loadable, default to deny, logging disabled

I saw no commits to netpfilt that look like candidates during hte three day
window, so I suspect that it is triggered by some other part of the ipfw start.
I can do a bisect if nothing else seems useful. I'm afraid that I don't have a
hash for the one that is the initial failure on Dec 16, so I'll try to track
down something close.
