Title:
  Updating shim-signed freezes computer during postinstall

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When performing an update using ubuntu's default GUI tool, during the
  "configuring shim-signed" message, the computer freezes and needs to
  be reset. Unfortunately, there is nothing in the system log except for
  corruption (a lot of null bytes). But I experience these hard freezes
  regularly, whenever a GRUB or EFI related package is being updated,
  always during postinstall.

  This bug exists and keeps reappearing since I originally installed
  Ubuntu 14.04. However, for some reason it does not happen with a very
  similar second machine. This machine does not load the 'efi' kernel
  module on boot, can this be the reason?
