full dmesg logs
CPU: Coffee Lake 8700K
Mobo: ASUS Z370-G STRIX
Distro: Arch
Kernel: 4.16.6-1-ARCH
The GuC firmware loads fine when I use the i915.enable_guc=1 kernel mode
setting, but when I try to enable HuC loading with i915.enable_guc=2 I get a
guc_fw_xfer error during boot. My system boots but my display output is blank.
Here's the relevant excerpt from the boot logs (full dmesg log attached).

I'm using the latest Arch package for linux-firmware (linux-firmware
20180416.b562d2f-1) and the latest Arch kernel.
This is my first bug report so sorry if it's not right.</pre>
