Funny Story :

I had this bug infinite number of times. I was not able to work at all. The system would get to log-in window and crash after a few seconds. Once I was able to work a whole minuet before restart.....

In the following link I saw a comment which told me that this is a consequence of a race between two drivers https://bugs.freedesktop.org/show_bug.cgi?id=48894

So, I pulled out the Ethernet cable, and the problem disappeared. After the system is UP, I can re-connect the Ethernet, and there is no problem.....

More information : I am working with Ubuntu 12.04 on an Ivy Bridge machine....
