If only /home is btrfs, it's sufficiently late that the btrfs kernel module doesn't need to be in the initrd. So I'd be looking at other failures. If by manual mount you mean the complete command: mount -t btrfs /dev/sdaX /home and not mount /home Then that's kinda weird for it to fail. I've been using 4.2.3 for a long time, up until a couple days ago, and now on 4.2.5, and have had no btrfs related issues at all, let alone with mounting.
