Okay, I tried partitioning the md device so that it was under 8T (7.1T in 
fact). Unfortunately I wasn't able to reproduce it in this configuration.

So, either it is a 8T+ problem, which disagrees with the other report, or 
the geometry has some sort of impact, or it is because the files I'm copying 
keep changing, so it may have gone away, or it is not 100% reproducible.

Shall I wait to see if you have a useful testcase from Thierry Vignaud 
before trying something else?
