(Solved) Ubuntu 11.10 Waiting up to 60 more seconds for network configuration…

Ubuntu 11.10 was released for 1 year ago but I have just found the new feature of Oneiric Ocelot.My problem is the mainboard of Server  have stopped working for few days ago therefore I need to buy a new mainboard for replace my old one.After i got a new one and installed it. Every time, i will got the  message  " Waiting up to 60 more seconds for network configuration…" after  my ubuntu boot.

To solve the problem, you can just remove the calls to sleep, by commenting the out ( or at least reduce the wait time if your network really does need to wait )

nano /etc/init/failsafe.conf

find word "sleep 40" and "sleep 59" and insert # in front of them and save file

The error message is disappeared but there is one of network card which is not worked.
And this is the last solution.

nano -w /etc/udev/rules.d/70-persistent-net.rules

----------------------------------
Insert all of this at the last row.

# PCI device 0x10ec:0x8139 (8139too)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="8139too", ATTR{address}=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
