[SOLVED]Interface Marvell Yukon-EC Ultra (Sky2 module) not ready at startup

[Guest]

I met the following problem with my computer equipped of a Marvell Yukon-EC Ultra network interface :

When I started my computer, the network interface was not working.
But an

/etc/init.d/networking restart

switched it on

In the logs I could read :

sky2 eth0: enabling interface
ADDRCONF(NETDEV_UP): eth0: link is not ready

It seems that the networking interface is not switched on enough quickly during boot-up.
Start the network services at hand after the startup was not very pratical .
So this is what I have done using the functionnalities of upstart.
1) When kdm is started, emit the kdm-started signal
2) When upstart receives the kdm-started signal, it restart the network

First, create a new script /etc/event.d/restart-network

# Restart-network
#
# This task restarts the network when kdm has started
# The module Sky2 doesn't start the network enought quickly during boot-up.

start on kdm-started

script
# Wait for 5 seconds and restart the network interfaces
    sleep 5
    exec /etc/init.d/networking restart
end script

Then, in the /etc/init.d/kdm-kde4 script, add the line "initctl emit kdm-started" :

case "$1" in
 start)
  if [ -e $DEFAULT_DISPLAY_MANAGER_FILE ] &&
   [ "$HEED_DEFAULT_DISPLAY_MANAGER" = "true" ] &&
   [ "$(cat $DEFAULT_DISPLAY_MANAGER_FILE)" != "$DAEMON" ]; then
   echo "Not starting K Display Manager (kdm-kde4); it is not the default display manager."
  else
   # if usplash is running, make sure to stop it now, yes "start" kills it.
   if pidof usplash > /dev/null; then
    DO_NOT_SWITCH_VT=yes /etc/init.d/usplash start
   fi

   echo -n "Starting K Display Manager: kdm-kde4"
   start-stop-daemon --start --quiet $SSD_ARGS -- $ARG || echo -n " already running"
   echo "."
   # -> HERE <-
   initctl emit kdm-started
   # -> HERE <-
  fi
 ;;

Be carefull of the owners and rights of the script restart-network
And voila !
