Direct firmware load for iwlwifi-8265-xx.ucode failed with error -2 
where the message repeats for several different integers xx. Curiously, modinfo on iwlwifi indicates that it expects version 28 of the firmware but I've been unable to find it anywhere (it's not part of the firmware RPM and the kernel.org source trees jump from 27 to 31 with nothing in between). I tried adding the 31 version to /usr/lib/firmware and setting the selinux context to match but it refuses to load it. I have not had a chance to try downgrading the kernel packages yet.
