  [ASUS MAXIMUS IV GENE-Z/GEN3] BUG: unable to handle kernel NULL

Bug description:
  Using Ubuntu 12.10.

  Setup:
  I have one monitor connected to my ATI Radeon HD 6800 card (via DVI) and one monitor connected via HDMI to my ASUS motherboard (the CPU has an Intel HD4000 built-in graphics card). The BIOS is set to have the PCI-E card as the default display.

  What happens:
  When I boot, I see the display connected to the ATI card. If I then go into display settings, and try turning on the other monitor, the Kernel crashes spectacularly.

  The log is attached.

  My installation is fully updated, but I have not installed any extra
  AMD or Intel drivers. Regardless, I'm fairly certain the kernel should
  not be crashing like this.

  Let me know if you need any extra info.
