... and at least a specific operating system (Linux) and a specific driver
(amdgpu with dc=1).

If your hypothesis was true - do you suggest everyone plagued by this bug just
buys a new main-board and an Intel CPU to evade it?

Since my Ryzen system is perfectly stable when used as a server, not displaying
anything but the text console, I'm inclined to rather keep my main-board and
CPU and just exchange the GPU for another brand that comes with stable drivers.
