Hi all, I wanted to put a capper on this just in case anyone was interested, or in case any future people find this thread, because I did find a resolution.
Turns out the way to stop the system from crashing was to disable Global C-State Control in the BIOS. Christian, Alex, you guys seem to have been on the right track in that it was something power related. I haven't yet been able to figure out what Global C-State Control exactly does. My best guess as to what was happening: once the GPU power management code was loaded and the GPU dropped into a very low power state, the CPU saw this and decided to match it, lowering its own power state to such a point that it hard resets the system. (Just a wild theory anyway :-) If anyone knows what this feature really does, or has any better theories as to why it doesn't play nice with AMD GPUs, please do share! Thanks and kind regards, -- Cal Peake
