Hello ;)

when enabling bridge with sysctl's, system panics:

malloc() of "64" with the following non-sleepable locks held:
exclusive sleep mutex ifnet r = 0 ... locked @ net/if.c:903
exclusive sleep mutex bridge r = 0 ... locked @ net/bridge.c:593
recursed on non-recursive lock (sleep mutex) bridge @ net/bridge.c:944
first acquired @ net/bridge.c:593
panic: recurse

trace looks like:

witness_lock
_mtx_lock_flags
bdg_forward
ether_output_frame
ether_output
nd6_output
ip6_output
mld6_sendpkt
mld6_start_listening
in6_addmulti
in6_update_ifa
in6_ifattach_linklocal
in6_ifattach
in6_if_up
