Hello Joseph, Thanks for your hint. I installed latest kernel available for Ubuntu Raring :
stephane@ubuntumini:~$ uname -a Linux ubuntumini 3.9.0-030900rc8-generic #201304211835 SMP Sun Apr 21 22:44:37 UTC 2013 i686 i686 i686 GNU/Linux I have not experimented any freeze when shutting down the system so far. However I still get some Wifi disconnection issues sometimes which freeze the PC. So problem is not 100% solved.
