I can confirm this bug is indeed present.=20
Worth noting that the screen is only blank on the laptop built-in display,
(after KMS), external monitors work fine.=20

Adding `amdgpu.dc=3D0` to the kernel parameters resolves the issue for me, =
but
this was not necessary before kernel 4.19.9, so it seems like a regression.=
 [1]
seems related.
