Hi, This panic may be caused by adding an interface to agr(4) after another interface is added to the agr(4) and deleted.
> ifconfig agr0 create > ifconfig agr0 agrport wm1 ifp->if_hwdl of agr0 is created on adding wm1. > ifconfig agr0 -agrport wm1 ifp->if_hwdl of agr0 is not deleted on it. > ifconfig agr0 agrport bnx1 ifp->if_hwdl is created again, so the panic appears. You may be able to use lagg(4) to avoid the panic. % ifconfig lagg0 create % ifconfig lagg0 laggproto lacp % ifconfig lagg0 laggport wm1 % ifconfig lagg0 -laggport wm1 % ifconfig lagg0 laggport bnx1 -- yamaguchi
