What about the subvol=/@? I think if you specifically add your own rootflags, grub won't add its own, and you said noatime,compress=lzo,discard,autodefrag but left off the subvol=/@ (unless you simply forgot to put it in the posting), and without that, it would have mounted the btrfs default subvolume, which would be (the filesystem's) / (subvolid=5) if you haven't changed it, and would have failed to boot as a result. -- Duncan - List replies preferred.
