I have problem with bootloop on Ubuntu 20.04 LTS with KDE DE, kernel version is 5.8.0-41 genic. I try many versions of kernel but nothing.
I think it is a gpu driver issue. I can boot into system with recovery mod or adding nomodeset to grub config file of that kernel, but then my system is running so slow and my cpu is on full load.
I have Ryzen 3 2200U with Vega 3 GPU, I'm using default Ubuntu gpu drivers.
Problem startet after update
