    I get

    KERNEL: assertion (cnt <= tp->packets_out) failed at
    net/ipv4/tcp_input.c (1476)

    with 2.6.13-rc5, also with a small netpoll patch that shouldnt affect
    these things. (Topic: "lockups with netconsole on e1000 on media
    insertion").

    I have a decent amount of dropped/overruns:
