****Possible FIX.**** (It fixed it on my pc)
I had the same exact problem. To see more details please look at this thread: http://ubuntuforums.org/showthread.php?t=611711

Then I installed xamp for Linux (following the instructions on the page below):
http://www.apachefriends.org/en/xampp-linux.html
When I started xamp with the command "/opt/lampp/lampp start" I received an error saying that I had some problems in my "/etc/host" and a message saying that it was trying to fix the problem.
After that all my system was responsive as it should be, and the long time to boot was considerately shortened.

I don't know how this was fixed. I leave it to the uBuntu coders to figure it out. But is has something to do with etc/host ans xamp was able to fix it.

Thanks for the attention.
