Comment 9 for bug 889527

if i just pover on cold machime with ubuntu - i have no problems with network

i can fix network for couple of minutes using ip ro del/add commands:

jumper@jumper-home:~$ sudo ip ro del default && sudo ip ro del 192.168.0.0/24
jumper@jumper-home:~$ sudo ip ro add 192.168.0.0/24 dev eth0 src 192.168.0.175 && sudo ip ro add default via 192.168.0.1
jumper@jumper-home:~$ ping 192.168.0.1
