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,
