Correct

Hi all, David,
I own Macbook 6,1 and how I fixed the issue.

Download Firmware Update 1.7 http://support.apple.com/downloads/MacBook_Pro_EFI_Firmware_Update_1_7_
MacBookPro5,5 the same hardware MacBook6,1, to extract MBP55_00AC_03B_LOCKED.scap.

mv MBP55_00AC_03B_LOCKED.scap MB61_00C8_B00_LOCKED.scap

sudo bless -mount / -firmware MB61_00C8_B00_LOCKED.scap --verbose

Shutdown and restart Mac update the firmware and restart automatically.

Attention consequences, the MacBook6,1 as new model identifier
MacBookPro5,5 but works well, possible problems could rise with future
firmware update.

Thanks for all, The Power of Community.

Title:
  Booting fails 3 times, works every fourth time after new install of
  Natty Narwhal amd64 on Macbook Pro

Status in EFI Boot Manager:

Status in Release Notes for Ubuntu:

Status in “grub2” package in Ubuntu:

Bug description:
  Dear all,

  I am experiencing a severe problem after a new install of Natty
  Narwhal on my Macbook Pro last night:

  The install worked fine, but after reboot nothing came up except fo a black screen.
  After forcing the machine off and on multiple times I was able to bring up the rEFIt boot menu by pressing and holding the 'Alt' (or Option) key and I can then boot into MacOSX or Ubuntu without a problem.

  After restarting / powering off I then have to turn the computer on /
  off the same number of times (3 or 4, I don't remember exactly) where
  nothing happens until it works again.

  I am using a MacbookPro 5,5 (13.3 Inch). My harddisk is setup as follows:
  200MB Partition for EFI
  20GB Partition for OSX
  18.6 GB Partition for / (ext4)
  108.49 GB Partition for /home (ext4)
  1.86 GB Partition for swap

  Other people also seem to experience the same issue:

  This is a pretty big problem for me, so your help is very much
  appreciated.
