Manually installing kbl_dmc_ver1_04.bin and kbl_guc_ver9_39.bin from 
<https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915> 
into /lib/firmware/i915 and running update-initramfs does not fix, so it 
it not a firmware issue. The firmware errors are removed, leaving a 
black screen with a solitary blinking cursor.

For the record, manual firmware installation is performed with:

cp kbl_dmc_ver1_04.bin kbl_guc_ver9_39.bin /lib/firmware/i915
chmod 644 /lib/firmware/i915
update-initramfs -u -k 4.16.0-1-amd64

(The HUC firmware is unchanged from the dpkg on unstable.)

Kind regards,
