Jorge Rama, as per http://www.asus.com/Notebooks_Ultrabooks/K50IN/#support_Download_8 an update is available for your BIOS (223). If you update to this, does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Thank you for your understanding. ** Tags added: bios-outdated-223 needs-upstream-testing regression- potential ** Tags added: raring ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1071200 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.
