Is it possible to hope for a correction in good times of this problem in the Linux Kernel by the Kernel team? I had written about the problem, already at the beginning of version 5.14 and therefore I tried to make everyone aware of this problem but at the time, unfortunately few followed me ...

5.14 was OK for my WX4100, the breakage came with 5.15 rc1
The highest chance to get amdgpu driver issues fixed is to report them in the AMD bug tracker (https://gitlab.freedesktop.org/drm/amd/-/issues) with an information what particular commit caused the issue (identified using the bisection process).
MauryG5:
Shark sorry, it means that I have to go to that path file you wrote me to eventually change the value and bring it to 0 as Classic says, I understand correctly?

--- Code: ---sudo grubby --update-kernel=ALL --args="modprobe.blacklist=ast"

...achieved the desired result.
Thanks!

This could still make things tricky in the unusual but by no means remote possibility something still goes wrong with the graphics card. It still sounds like a bug that this should be necessary (it wasn't before). I'll investigate this when I do my upgrade.

@MauryG5: Follow this guide and replace the line with your desired line or change the GRUB file manually:
https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/kernel-module-driver-configuration/Working_with_the_GRUB_2_Boot_Loader/#sec-Making_Persistent_Changes_to_a_GRUB_2_Menu_Using_the_grubby_Tool
@mcarden: Great. I have to blacklist AST on Void also, otherwise even with a xorg.conf file, it doesn't work. I hardly guess on Fedora it only works accidentally.
MauryG5:
Sorry, you mean I have to make this line become: ~] # grubby --set-default /boot/vmlinuz-5.15.fc35.ppc64le? Would this be the change to be made to get it started with the AMD GPU?
