Comment # 4 on bug 1177707 from Josef Reidinger

Hi teo, I was hit also by same issue. It looks like something is broken with on
board amd discreate cards. Leap 15.2 works fine, so it has to be something in
newer kernel or amd framebuffer. Assigning to kernel maintainers who can have
idea who is responsible for this part.

BTW it is not brick, just frame buffer does not display anything.
If more info is needed about hardware, I can also provide it.
