Hi. Doing some tests on FreeNAS (FreeBSD 9.2+) I hit series of panic during active interfaces manipulation in some scenarios including multicast and several vlans on top of lagg. I am not ready to reproduce the full environment on head, but the code looks equal, so probably the bugs. I've made a patch to improve locking in that area, that seems fixes the problems: http://people.freebsd.org/~mav/mcast_vlan_lagg.patch Could somebody with more experience in the area please take a look? Thanks! -- Alexander Motin
