Run in a terminal cat /etc/fstab and ifconfig eth0, add the output to the question. –  edwin Oct 27 '13 at 12:34
    
You might want to install bootchart and shed some light into what's happening while you boot. –  MadMike Oct 27 '13 at 20:29
    
here is my bootchart it seems like ureadahead is causing the problem –  ArK Oct 27 '13 at 20:41
    
I was able to reduce the time taken by ureadahead to less than 10 seconds by removing preload –  ArK Oct 28 '13 at 18:57
