Indeed this looks like a related problem. I'm just confused why the forced edid
worked with kernel 4.14.x, worked with kernel 4.15.x with the error messages
and finally is broken in 4.16.8. I get the error messages but no output at all.
Since I use the same LibreELEC base and just switch the kernel version it looks
like it's related to some driver changes.
