Let me confirm one thing. Did you also see a message "panic: bogus refcnt 0", in your panic? As far as I investigated, only IF_CLONE_REMREF_LOCKED() can display this message. But it's called only in if_clone_create/detach/destory(), and none of them seems to be called according to the description in the PR. (rtexpunge() in route.c also has this message, but it is commented out by "if 0", so it is not the cause of this message) Thanks, ---- SUZUKI, Shinsuke @ KAME Project
