I have problems when booting Ubuntu 18.04 with kernel 4.15.0-36-generic, sometimes blank or can login but there are issues like this:
fbcon: amdgpudrmfb (fb0) is primary device

please help me because this bug is very annoying, I have to force restart it, if it's blank when booting. I'm afraid my hardware is broken.
