And especially http://tullinup.dk/temp/2.jpg http://tullinup.dk/temp/1.jpg

Note that the failures I see are after a clean boot... most of the above are reports of a problem after a dirty boot.
I've seen the issue on several machines now... all after performing "sudo apt-get upgrade/update".

This is a very serious issue for any unattended or kiosk type machine.  I ask for an "urgent" rating on the bug.
This is not quite a duplicate of the older report 428570 .

Title:
  grub2 waits forever for keystroke before booting default OS.  headless
  server. hang.

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub2

  After a seemingly-routine "apt-get update" on an Ubuntu 10.10  server, the machine hangs on boot. 
  It is sitting at the grub2 prompt, waiting in vain for someone to come along and press <enter>.

  I have tried two workarounds:

  ---------------------------------------------
  Edit /etc/grub.d/00_header to remove the check for recordfail in:

  make_timeout ()
  {
      echo "set timeout=1"
  }
  --------------------------------------------------------------------
  In /etc/default/grub set
   GRUB_HIDDEN_TIMEOUT=2
  ---------------------------------
  Then "sudo update-grub"

  Now I'm pretty dang stuck.  There is plenty of forum activity on this
  issue, but no true solutions.
