Bug 1024885

Greetings,

I ran into an issue today with openSUSE Tumbleweed not correctly booting. I would receive a text version of boot which would inevitable freeze. When trying to switch to a different tty to login and diagnose / fix the issue I was presented with the login prompt (as expected); however, keyboard input was randomly accepted and the text boot (from the other tty) was flashing over top of the login prompt. 

After sorting things out and getting a working system again the issue appears to be radeon and amdgpu fighting over the same real estate causing Xorg to fall into an endless loop of failing to start which then doesn't allow, in my case, gdm to start.

I was able to use boot options of amdgpu.blacklist=yes plymouth.enable=0 verbose 3 to get myself to a console login to fix things. In the end it required blacklisting amdgpu in order to use radeon for the video driver, which did not fix the issue alone, I also needed to zypper rm x86-video-amdgpu because while blacklisted, apparently Xorg still tries using amdgpu.

I hope this report serves to get the right people squashing this bug soon and in the meantime serve as help for those finding themselves facing the same issue and looking for a way back to a working system.

Thank you so much.
