Title:
  Linux fails to read GPT(EFI) partition table created by both GNU
  parted and OSX diskutil

Status in “grub-installer” package in Ubuntu:
  Fix Released

Bug description:
  Linux (linux-image-2.6.32-16-generic AMD64 2.6.32-16.25) fails to read
  GPT(EFI) partition table created by both GNU parted and OSX diskutil.

  Test case:
  1. dd if=/dev/zero of=/dev/sda count=128
  2. parted:
      a. mklabel gpt
      b. mkpart primary fat 0 50
      c. quit
  3. partprobe /dev/sda
  4. dmesg | tail -n1

  Kernel reports:
  [ 5185.710614]  sda: unknown partition table

  Kernel config (grep -i part /boot/config-2.6.32-16-generic | grep -i efi):
  CONFIG_EFI_PARTITION=y

  Comments:
  Ubiquity's partition manager working well with GPT partitions.
  Ubiquity fails later during actual creation and formating of partitions: fails to access /dev/sdx devices.
