Venk, I think this commit would help you mount in that case: http://gitweb.dragonflybsd.org/dragonfly.git/commit/dbd4f60002b98556e6fc8413e6eacf2aedfce6df Since the mismatched locking was corrected by Matt and there's now a workaround to avoid REDO stage (so you are able to mount in that situation) I will close this ticket.
