I reproduced the hang with code built on aarch64.
I have not been cross-compiling from amd64.

For poudriere I use armv7 jails running on aarch64.
One of them just hit the hang with 14.1-STABLE
kernel and 15.0-CURRENT userspace.

Poudriere told me I shouldn't run a newer userspace than kernel.
It usually works despite the warning.
