Hi Filippo.

I actually conducted some tests last week (also with aes-cbc-essiv) but
wasn't able to reproduce the two errors (tested it on the same computer,
with the same USB-sticks, same commands, kernel 2.6.24 etc.).
I'm not sure if I should be glad about this,.. because I definitely had
those two problems, but of course it's still possible (though I consider
it unlikely) that there were hardware problems.


Today I copied a complete Debian installation (about 6 GB) from an
unencrypted partition to a luks/dm-crypt partition with aes-xts-plain
(according the Herbert Xu plain is the "most secure" and it's not
required to use the benbi mode for the IV generation).
I had no problems with this mode, too.

Best wishes,
Chris.
