The panic implies that the MAC policy wasn't initialized (rules_mtx has=
n't
been initialized).  However, mac_portacl.c installs a module with a SYS=
INIT
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 it=
s
init() routine)
