<pre>Not sure if that helps, but could you try reverting this commit?
<a href="https://github.com/torvalds/linux/commit/e03fd3f300f6184c1264186a4c815e93bf658abb">https://github.com/torvalds/linux/commit/e03fd3f300f6184c1264186a4c815e93bf658abb</a>
My MacBookPro Mid 2017 started to experience the black screen issue since
4.18.0-rc1 up to 4.19.0-rc4 (and probably higher). Having that commit reverted
has resolved the black screen issue I had, allowing me to use amdgpu.dc=1
again.
