If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:

Title:
  Race condition with network and NFS mounts causes boottime hang

Status in “linux” package in Ubuntu:
  Incomplete
Status in “nfs-utils” package in Ubuntu:
  Incomplete

Bug description:
  I seem to experience a race condition during boot of my ubuntu 12.04 server: In approx. one of seven boots, the server hangs during bootup.
  This is what I see on the screen:

  After the line

   * Starting configure network device

  there is a short delay of about 1 second, then messages continue. I
  see

   * Starting Mount network filesystems [ OK ]
   * Starting set sysctls from /etc/sysctl.conf [ OK ]
   * Starting configure network device [ OK ]
   * Stopping Mount network filesystems [ OK ]
   * Stopping set sysctls from /etc/sysctl.conf [ OK ]
   * Starting Block the mounting event for NFS filesytems until statd is running [ OK ]
   * Stopping Block the mounting event for NFS filesytems until statd is running [ OK ]
   * Starting Block the mounting event for NFS filesytems until statd is running [ OK ]
   * Stopping Block the mounting event for NFS filesytems until statd is running [ OK ]

  The last messages repeats several times, and then the boot process hangs.
  In 6/7 of cases, I wait for a minute, and after that bootup continues.

  But in approx 1/7 cases, the system hangs at this point forever. The
  machine does not respond to CTRL-ALT-DEL, I have to reboot it using
  SysRq-Keys.

  WORKAROUND: Setting the NFS entries in fstab to "noauto" completely removes the problem:
  There is no timeout during boot, and no lockup any more. The machine boote smoothly with the NFS-shares unmounted. After the machine is up, we can manually mount the NFS-shares without a problem.
