I was hit by this too. Really annoying :-(

There might be something written on disk by Debian kernel that
upstream kernel doesn't. Probably not file system corruption since
it's clearly recoverable (as I write, my system just came back to
normal after simply booting a D-I image and importing the pool there).

But as the data is there, if upstream kernels can't access it I think
it's probably relevant to them.

If you bring this upstream, I recommend writing to freebsd-fs, it's
much easier to get attention there than by filing a PR.
