I have found at least 3 problems upgrading to Ubuntu 12.04. I have upgraded 4 of my servers and found the following problems. 1. The ia32-libs package uninstalled itself somehow, causing all my 32bit programs to fail start back up if they restarted. 2. @reboot cronjobs ran 2 minutes after the machine booted in kern.log. I accidentally started the programs manually because I thought they wouldn't run. 3. On a fresh install, the byobu network display doesn't show up.
