Ubuntu 19.04

Problem:
Booting from live media OR installed ubuntu fails with a blank, black screen and total system hang.

How to reproduce:
Using AMDGpu driver and AMD 4th Gen GCN GPU, try to boot Ubuntu 19.04 (or 18.04)

Resolution:
Manually updating kernel to 5.1 and adding the "amdgpu.dc=0" kernel boot parameter seems to fix the problem.
