OK, another wild guess: are the cache lines properly invalidated?
I think you said that the corrpution was a copy of earlier data ...
well, where could 'earlier data' be hiding?  The offsets you're

Don't know how hard it would be for you to run the test with cachine disabled,
but it might be worth a try.
