--- Comment #14 from Markus Stoff <ms-freebsd-bugzilla at stoffnet.at> ---
I can also reliably reproduce this on a physical machine using the
vnet_epair_test.sh script at bug #234985.

Server:

CPU: AMD Ryzen 5 3600 6-Core Processor               (3593.32-MHz K8-class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 12 CPUs
FreeBSD/SMP: 1 package(s) x 2 cache groups x 3 core(s) x 2 hardware threads


Running 'ifconfig ${epair}b -vnet ${jid}' before removing the jail avoids the
kernel panic. However, I would prefer to shut my jails down in a clean way
rather than just pulling the (network) plug.
