What I meant to ask was if there were false positives/false negatives in booting from the subvolume that would lead you to doubt the results of the git bisect, but it sounds like it's 100% reproducible for you? I'll take a look at the image. In the meantime, could you try booting with https://gist.github.com/osandov/9f223bda27f3e1cd1ab9c1bd634c51a4 applied on top of 4.9 so we can hopefully narrow it down? It'd also be great to know if it always fails the same way or if it varies. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
