I'm using Ubuntu 22.04LTS i followed the instructions from another post: how can I use "amdgpu" instead of "radeon" drivers on 20.04? But after rebooting I'm welcomed by this (see image) Console output before system freezes

Also i can see this weird line, probably related to the kernel driver: Weird graphical glitch

The output of the command: lspci -k | grep -EA3 'VGA|3D|Display' is

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R4/R5 Graphics] (rev 05)
    DeviceName: Onboard IGD
    Subsystem: Hewlett-Packard Company Mullins [Radeon R4/R5 Graphics]
    Kernel driver in use: Radeon

I'm certain that my APU (AMD A8-6410 APU with Radeon R5 M330) is compatible with AMDGPU because i used it in Ubuntu 20.04LTS and in other distros like PopOS, but for some reason in Ubunut 22.04LTS im having issues with it.

Any assistance will be much appreciated (also sorry if my English is bad, I'm not a native speaker)

just to share a workaround for this issue, because after digging up for a bit i realized that the kernel 5.19 has issues with legacy AMD hardware (2015 and early) that tried to use the AMDGPU kernel driver which crashes your system on boot up.

What i did was simply upgrade my kernel to 6.2.9-060209-generic by following the steps shared here: https://askubuntu.com/a/1388117/236992 In my case i used the shell script and it worked:

rodrigoal@rodrigoal-HP-Pavilion-14-Notebook-PC:~$ uname -r
6.2.9-060209-generic

Afterwards i edited my grub file: sudo gedit /etc/default/grub

I added the following after the "quiet splash" radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.dc=1"

It looked like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.dc=1"

For my hardware is was cik because my integrated gpu is a Radeon R5 M330.

Once that was done, i saved the edit and executed the following command:

sudo update-grub2

Once it finishes you reboot your PC/laptop.

Now the output of the command lspci -k | grep -EA3 'VGA|3D|Display' should be like mine:

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R4/R5 Graphics] (rev 05)
    DeviceName: Onboard IGD
    Subsystem: Hewlett-Packard Company Mullins [Radeon R4/R5 Graphics]
    Kernel driver in use: amdgpu

Hope this helps anyone else who suffers from the same issue.
