If btrfs initramfs hook should only be needed for a root btrfs AFAIK, but
if the initramfs is probing before the btrfs module is loaded/available or
devices scanned that would produce such error.

Is it actually failing in initramfs, or after?

Paste output of failing `mkinitcpio` command.

I am mobile ATM so I can only read check so much, but verbatim output is
required to debug further.
