It seems that recent Radeon drivers are problematic. 20.1.3 crashed the machine and now 20.1.4 is at it again.
The latest driver power state failure crashed the machine within 12 hours of installing 20.1.4.
ntoskrnl.exe was again the affected component along with hal.dll etc. This means there are problems with the miniport components.
Obviously the BSOD problem is very severe.
