On a clean install of Ubuntu 20.04 the following messages are printed while updating the initramfs.

I: (UUID=610d0eae-f18f-4d55-86a0-9cb12375dafb)
I: Set the RESUME variable to override

Checking in /lib/firmware/amdgpu/ I have a fair number of firmware files but those listed. I'm not sure if these are missing or not needed.

Thank you for taking the time to report this bug and helping to make Ubuntu better. This is not a bug but a harmless warning that can be ignored (as long as there are included firmware files). You can check with following command that amdgpu firmware files were added to the initramfs:

$ lsinitramfs /boot/initrd.img | grep amdgpu
usr/lib/firmware/amdgpu
usr/lib/firmware/amdgpu/aldebaran_mec.bin.zst
usr/lib/firmware/amdgpu/aldebaran_mec2.bin.zst
usr/lib/firmware/amdgpu/aldebaran_rlc.bin.zst
[...]

Feel free to continue to report any other bugs you may find.
