Hi again,

I've done a bisect on the 4.19.y branch and I've found that it is the 
commit 2bf1f848ca0af4e3d49624df49cbbd5511ec49a3 [ACPICA: Fix memory leak 
caused by _CID repair function] that introduced the bug. By doing a git 
revert and building the kernel I can boot normally but as long as this 
commit exist I just get a black screen as explained above.
