    SubjectUsing netconsole and getting double prints
    I'm getting double prints when using netconsole. This used to happen
    to me and then I just enable debugging log level manually (dmesg -n 8)
    but now no matter what I try I always get double prints.

    For example:

    [ 23.425448] console [netcon0] enabled
    [ 23.425567] netconsole: network logging started
    [ 23.425448] console [netcon0] enabled
    [ 23.425567] netconsole: network logging started
    [ 32.856073] eth0: no IPv6 routers present
    [ 32.856073] eth0: no IPv6 routers present
    [ 66.307342] kmemleak: 6 new suspected memory leaks (see
    /sys/kernel/debug/kmemleak)
    [ 66.307342] kmemleak: 6 new suspected memory leaks (see
    /sys/kernel/debug/kmemleak)

    Instead of dmesg -8 I'm now using ignore_loglevel as a kernel
    parameter but I still get double prints. This also happens if I use
    "debug" as a kernel parameter instead.

    The netconsole is set up on the dev box as follows through an /etc/rc.local

    dhclient eth0
    IP=192.168.2
    # sudo dmesg -n 8
    modprobe netconsole netconsole=@/eth0,6666@${IP}/
    exit 0
    I capture my data with netcat script (I call it netlog):

    #!/bin/bash
    echo "You should now run in another window: tail -f $HOME/log"
    while true; do
    /bin/nc -u -l -p 6666 >> $HOME/log
    done
    This also just doesn't work if I run the nc manually without a redirect:

    while true; do /bin/nc -u -l -p 6666; done
    Any ideas?

    Luis
