BigSur freezing sometimes

[TherioN]

Hello!

I have successfully installed OSX BigSur on Gigabyte Aorus X470 Mobo, Ryzen 7 2700X CPU, AMD R9 380 2GB, 32GB DDR4 RAM.
After some time, computer freezes, first I can move the mouse, but then it gets totaly frozen.

Please help, this is what I can see after reset:

panic(cpu 14 caller 0xffffff80159fca25): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds
service: com.apple.logd, total successful checkins since load (1940 seconds ago): 195, last successful checkin: 0 seconds ago
