I tried that with b770f04ba2ee (next step in bisect), but no success
with this option, unfortunately.
I'm not using grub but directly booting from UEFI using CONFIG_CMDLINE.
Any other option I am using (root, loglevel and netconsole) works as
expected and I veryfied that "amdgpu.discovery=0" is included in
vmlinux.
