Comment 0 for bug 1728238

The i915 Kabylake GuC firmware is failing to load on boot, and generating dmesg errors. The Kabylake HuC firmware succeeds. All files exist. I've also verified the Kabylake GuC firmware matches the correct file size and md5 listed on 01.org.

I then ran update-initramfs verbosely, and see that only /lib/firmware/i915/skl_guc_ver6_1.bin is being added. /lib/firmware/i915/bxt_guc_ver8_7.bin and /lib/firmware/i915/kbl_guc_ver9_14.bin seem to be ignored.
