or
[ 7.124810] in your initrd/initramfs image.

Looks like you need to load the GPU firmware.
Create a directory called /libdata/firmware/i915drmkms and copy the
/lib/firmware/i915/*.bin files from some Linux system into it.
Create symbolic links, if needed, from what the kernel expects
(see above) to the latest `skl_*' (Skylake) versions of the same files.
