I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developer don't keep an eye on it, I decided to forward it by
mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=216616 ; :

I've looked at the kernel log and found that simpledrm has been loaded
*after* amdgpu, which should never happen. The problematic patch has
been taken from a long list of refactoring work on this code. No wonder
that it doesn't work as expected.

Please cherry-pick commit 9d69ef183815 ("fbdev/core: Remove
remove_conflicting_pci_framebuffers()") into the 6.0 stable branch and
report on the results. It should fix the problem.

Greg, is that enough for you to pick this up? Or do you want Andreas to
test first if it really fixes the reported problem?

This should be good enough.  If this does NOT fix the issue, please let
me know.

Thanks a lot. I think I can provided a dedicated fix if the proposed commit doesn't work.

Best regards
Thomas


thanks,
