Using old kernel, all is good, while with newer kernels, nothing is possible except via remote login - no video, no keyboard.
I reported similar trouble in Bugzilla month ago with much older Radeon: https://bugzilla.redhat.com/show_bug.cgi?id=2130843
Are others with GCN2 graphics having this trouble?
I don't think I have GCN2 graphics, though I do have an older radeon that is working without issue. I'm not sure what GCN2 is.
Can you run grep -i amd /boot/config[kernel version] on the kernel that is working and the kernel that isn't and check if there are CONFIG options that are different?
It might be a regression if everything is the same.
