Title:
  external monitor stops boot process

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My laptop will not boot into ubuntu if I start the system with an
  external monitor attached.

  After selecting "Ubuntu" screen shows this text:

  alloc magic broken at 0xdfbb1680: ff2c001e
  Aborted. Press any key to exit

  _________

  I am then forced to disconnect the monitor and reboot the system.

  However if I connect the monitor while "Ubuntu" is loading/loaded I
  can work with the external monitor without issue.
