Hi,

have you considered upgrading to Fedora 33?
Or can you try booting Fedora 33 from live usb and post the output of xrandr?

Hi guys solve my problem I practically found it in this link link kernel panic - AMD-VI: completion wait loop after a failed install of Arch Linux on a blank SSD - Unix & Linux Stack Exchange, I had to modify the kernel parameters.

In my case add this

amdgpu.runpm=0
