Sorry but my bisecting efforts came to a halt. Last kernel I was able to boot
was  4.14.228. And this one still has the issue.

Kernels 4.13.16, 4.12.14, 4.11.12, 4.10.17, 4.9.264 I was able to build but
they don't boot into desktop or even console. Just getting a "no signal"
message von my monitor after the kernel has booted, and some of these kernels
do a reboot.

Don't know how to proceed from here.
