Title:
  Kernel 3.13 still broken on Northern Island-based Radeon Graphics
  Chips (Radeon HD 6000 and Richland APUs)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I've noticed after installing Ubuntu 14.04 on a Richland APU desktop, that this critical DPM issue has still not been fixed. DPM needs to be disabled by default like in kernel 3.14 for these systems so that the live CD or desktop session does not instantly reboot the machine. I was able to bypass it by editing the grub.cfg on the bootable flash drive and adding radeon.dpm=0 to the boot options, along with cding to /target/etc/default and editing grub with the same change before rebooting after installation to bypass it.
