I used following steps:

That's probably not the best way to be doing it on a debian based OS. Take a look at http://blog.avirtualhome.com/2012/01...-ubuntu-11-10/ and https://help.ubuntu.com/community/Kernel/Compile.

Also you should know that by using the 3.1 mainline kernel sources, you're not getting all the patches and optimizations that Ubuntu performs. For one ureadahead and apparmor break as the necessary patches will be gone.

As far as you not booting, you may have disabled things while doing the makemenuconfig, or you may have not enabled something that you need to access the drive that you mounted your /root directory on... Did you actually put /root on a different partition than / though??
