--- Comment #5 from Theodore Tso (tytso@....edu) ---
Can you try replicating this on an upstream kernel, running in a controlled
environment (e.g., using kvm) and then give us reliable reproduction
instructions --- e.g., using simple shell scripts, and which doesn't depend on
the vagaries of the settop box software, and random versions of du, df, etc.

For bonus points, use get a copy of kvm-xfstests[1][2], and run the test using
scripts cut and pasted into "kvm-xfstests shell".   That way we will be able to
reproduce *exactly* what you are doing.
