See:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272965
and:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272966

All involve 'Alignment Fault' on read at some point
but the 272966 ones first involve: Kernel page fault with
the following non-sleepable locks held during
in6ifa_ifwithaddr.

The 272965 ones involve udp_input getting the alignment
fault.

These reports are based on using the most recent snapshot
of main [so: 14], not based on my own builds. They do
not involve aarch64 at all: no chroot use, no jail use,
no lib32 existing for the already just-armv7 context.
