You *really* don't want to be using that kernel for XFS. Please
upgrade to at least 2.6.17.7 to avoid the dir2 corruption bug
in that release.

I assume you mean when the system boots - those timestamps are from your
boot log above. What is it that you think is incorrect about these
messages? They are information indicating a successful log recovery
which means your /usr filesystem is not being cleanly unmounted by your
shutdown scripts. This is just saying that log recover occurred on
that filesystem and everything is ok.

Yes, you'll see this message for any filesystem that wasn't cleanly
unmounted and if it succeeds then you have nothing to worry about.

Cheers,

Dave.
