--- Comment #8 from freebsd at rail.eu.org ---
My case seems similar :
* Using 12.2-RELEASE
* Jail defined through ezjail
* using vnet, and jib (/usr/share/examples/jails/jib) to manage the interface

ezjail-admin (one)start works without problem, if logged as root ezjail-admin
(one) stop works
However when logged as another user, sudo ezjail-admin (one)stop or su -;
ezjail-admin (one)stop provoque a panic (pagefault) of the host.
I join the crashinfo output, definition of the jail, rc.conf of host and jail.
If needed I can provide the vmcrash file or even the virtualbox diskimage used
to reproduce the bug
