The trace doesn't seem to firmly point at xfs locking up. There are
md and dm crypt involved. Are you sure this is locking up inside xfs?
Also, can you please enable frame pointers so that we can get more

For now, let's not draw any conclusion or mix the issues. I'll look
up the original thread and look into what the lockdep warning means.
