I am getting some kernel log errors and my system sometimes crashes to green screen and I am wondering if it could be related to those errors.
I got Ubuntu 22.04.1 installed with Kernel 5.19.5.x. Hardware AMD® Ryzen 7 4800u with radeon graphics × 16
sudo dmesg --level=emerg,alert,crit,err

The first one, I think is a know bug, but I am not sure about the others.
------------------------------------update----------
After clean fresh install of 22.04.1 with default kernel 5.15.0.48 generic it looks like this:
