dmesg-4.18.8

I have just upgraded my kernel on openSUSE Tumbleweed from 4.17.14 to 4.18.8
and my display that is a Panasonic 4K/UHD TV (TX-55CX400E) is not detected
anymore and not available after boot. I have to pass amdgpu.dc=3D0 kernel
paramater to get it available again.

If I check dmesg I can see a lot of lines like the following repeated:
