(Get the code!)
I was also the person who replied and reported the bug twice here on launchpad and once on bugzilla. OP, I have the exact same hardware as you in a Richland APU machine off-site. Richland APU's use Northern Islands graphics chips (Radeon HD 6000 desktop cards) and are of course completely broken with DPM. Kernel maintainers have disabled DPM by default in kernel 3.14+ because they realized it was completely broken, but for some reason they never disabled it during 3.13 development release (you'd think maintainers of the code would have tested their code before they pushed the patches), so those newer kernels will work fine. As long as you edit grub on the ISO and edit etc/default/grub as well as boot/grub/grub.cfg on the install before rebooting after installing it, everything will work fine.
