Panic] Alignment Fault in pf_state_insert on rpi 2 (ARM64)

Hi everyone,

I am encountering a consistent kernel panic on boot with my Raspberry Pi 2
running FreeBSD 15 release.

The panic is an "Alignment Fault" that appears to trigger within
pf_state_insert during IPv6 output*.*

Fatal kernel mode data abort: 'Alignment Fault' on read

Uptime: 38s

The panic happens +- every time I boot. I also tried unplugging for like 30
sec with the same effect. The installation was uneventful: I just flashed
the recent 15 release image, booted and restored my configuration files.
LMK what other info I could capture.
