not that it helps any, but I've seen this too, but with
a mix of union and null mounts on a Dell 400SC.
However, the only file operations that hung for me is any that were
within a particular directory tree, and up to and including /. Accessing
a different directory tree worked ok. I'll bet your system probably
hung in a similar way, given the bit I know about how the locking works.
(not accessing / can be a bit difficult)
