A workaround/fix is to patch /usr/share/initramfs-tools/hook-functions this=
=20
way (see patch attached)

That way, the firmware will be copied from=20
  /lib/firmware/5.3.0-0.bpo.2-amd64/amdgpu/
to this dir in the initramfs
  usr/lib/firmware/amdgpu/
instead of
  usr/lib/firmware/5.3.0-0.bpo.2-amd64/amdgpu/

After that, at boot-time the amdgpu firmware is found.

Please note that after patching it is necessary to run this command:
# update-initramfs -u -k <the_kernel_version>

BTW: #933733 and #942513 may be duplicates.

Regards
