After upgrading to kernel 4.19.9 in Arch Linux I have a blank screen. The
system is unusable.
My system is Asus ROG GL702ZC with RX 580:
lspci output:

Reverting it fixed the issue. I also tried 4.20-rc7. There is no issue there.
But 4.19.11 still has it.
Setting amdgpu.dc=0 also helps with 4.19.9 - 4.19.11
