Not sure which right now.
That looks to be happening during a vnet jail teardown, so it’s likely
the sys/netipsec or sys/netpfil/pf tests.
I’ve done a quick test with the pf tests, and they provoke this panic:
panic: mtx_lock() of destroyed mutex @

To reproduce:
kldload pfsync
cd /usr/tests/sys/netpfil/pf
sudo kyua test
I'll revert r346530 until further testing has taken place.
Thank you!
