The panic implies that the MAC policy wasn't initialized (rules_mtx hasn't
been initialized).  However, mac_portacl.c installs a module with a SYSINIT
ordering that is long before init() starts.  To debug this further you will
want to trace mac_policy_modevent() to see when it is being called and if
it is failing to call the init() routine in mac_portacl.c.

(Arguably the portacl code should register the sysctl dynamically in its
init() routine)
