I have 2 vega 64 in crossfire configuration and i didnt had any issues until new driver 21.6.1 and even latest 21.7.1 both of them cause crossfire supportin applications to freeze up whole OS, not crash it freezes up everything no error in logs nothing when it starts to load resources to memory and it's supposed to use crossfire configuration, both GPU's work fine standalone, crossfire works fine with driver 21.5.1 . so now i can't upgrade to latest drivers because of this, seems like amd driver team messed up ....
