Both sets of messages are exactly identical, except that
in the second set, a few parts got interleaved.  Try to
copy the garbled parts and delete every second character,
then you can recognize it.

It's a known problem, but it's not trivial to solve in a
generic and efficient way.

Don't worry, your file systems are OK.  It's just a
display problem.
