Trying The Experimental Radeon RX 480 Overclocking With AMDGPU OverDrive Isn't Going So Well

With the Linux 4.8 kernel coming later this year one of the main end-user additions to the AMDGPU kernel driver is GPU overclocking support via OverDrive. This is the first time AMD GPU overclocking is being offered via their open-source Linux driver and so I decided to try it out with the AMD Radeon RX 480 using this experimental DRM-Next code.
