No, I did see the same corruption with XFS; it just took more work

copying one huge file; I had to untar a full filesystem onto it).
So I would suspect the odd access patterns.  I could also run a test
with EXT2/3 if you'd like.  I didn't manage to trigger the corruption
directly on the md device, but my access pattern was quite simple in
that case (dd big blocks to different areas).

If you can reproduce it with ext2/3 it would make debugging simpler, because I 
understand the ext code and data structures a lot better.

Thanks for that data element; it pretty much confirms my suspicions.

Are you able to reproduce the problem with the scripts I sent earlier?
If not, I can give you access to a machine that can.

I hate to admit it, but I haven't had a chance to try yet.
