Thank you. Unfortunately it does not change anything noticable.

It seems 4.19 and current git are 100% reproducers so far - I have not managed to
successfully boot either of them yet. I have seen 4.19-rc1 era git kernel booting at least once.

I noticed that Debian packaged 4.17 with initramfs worked fine so far for my test,
from these I have in grub menu. My selfcompiled kernels do not use initramfs.
