I always test the latest kernel as soon as they released with a script that pulls the latest Ubuntu mainline kernel. As I originally stated in the description, only kernel 3.13 is affected. Kernels 3.14-rc1 through 3.15-rc2 are not affected since they have disabled DPM for Northern Islands graphics chips due to outstanding bugs like what this bug report is all about. I already reported this bug upstream in December.
