Public bug reported:
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.
