Description Lukas Zapletal 2018-12-19 08:25:56 UTC 
Hey,

I recently upgraded kernel from 4.19.8-300.fc29.x86_64 to 4.19.9-300.fc29.x86_64 and the system hangs with:

fb: switching to amdgpudrmfb from EFI VGA

I am able to soft restart tho and use older kernel to start the system. This is a regression, this system is on Fedora from version like 26 without any major issues.
