[arch-general] amdgpu: blank screen on Radeon RX 460

since some updates in the last days - I have not found out yet which one
caused it - my Radeon RX 460 only shows a blank screen after starting
lightdm and also switching to terminal is not possible. As a workaround
booting with "amdgpu.dc=0" helps - but then audio via HDMI is broken.
The issue appeared once some months ago, but after wondering why audio
is broken I removed "amdgpu.dc=0" and everything went smooth - until now.
I've searched through the BBS and amdgpu bugreports, tested some kernel
commandline parameters like amdgpu.gpu_recovery=1, switching to DRI "2",
but no solution yet.
Does somebody else have a similar gpu and experiences a similar issue?
