Panic in stable/11 (amd64) @r303903: page fault while in kernel mode

[Adrian Chadd]

[snip]

#define IF_LLADDR(ifp)                                                  \
    LLADDR((struct sockaddr_dl *)((ifp)->if_addr->ifa_addr))


it's because if_addr is NULL in your dump. God knows why that is! My
guess is we caught it in some stupid update window.

Ok, so what should we do for locking?
