My guess is that you have btrfs compiled as a module, it then needs to be in
an initrd, and you either haven't built it and put it in the right place, or
grub isn't setup to load that initrd.

That's missing an initrd. Are you absolutely certain then that btrfs is
compiled in the kernel and not as a module?
