Just to complete the thought... use these just to boot and have access
to something newer. I'm not suggesting install them. First try a
normal mount, and if that fails, try -o recovery, if that fails, I'm
curious about

btrfs rescue super-recover -v <dev>
btrfs check <dev>

What I'm after is a way to get it to mount cleanly with a new kernel,
and then hoping you can then just reboot with the ancient kernel and
it'll be back to normal.
