i ma having issue with installing catalina on B550 MOBO ((Aorus Pro Wifi AC - Gigabye) with AMD ryzen 3950X .. the same system was working fine with AMD ryzen 7 3700X... i just upgraded the processes to 3950X .. boom doesnt start and karnel panic.. now doesnt even install .. or let me pass through kernel message

other important config is RAM 48GB .. Kingston Hyperx Fury .3200 mhz and Asus Tuf gming Radeon 5700 XT//

Linux and Windows are working fine on the system
