Control: severity -1 wishlist A firmware upgrade on my X470 Taichi Ultimate to P3.4 (from P3.2) resolved the UUID collisions (AMD Ryzen 3700X).
As terrifying as this was for me, the solution is to have hardware that functions properly. I think there is merit in leaving this open so that other people with buggy firmware know to upgrade their firmware, but adding a test for a UUID collisions is not a grave defect.
