I could gripe about folks reporting this after the release, rather
than before it... I just logged into my workstation from home, and
watched it for a minute or two, zero I/O during this time. On the
other hand, my laptop does appear to be doing periodic I/O and it
does seem to be every 5 seconds. I have also had a report of someone
not being able to keep their disks spun down in 2.6 on a laptop.

Scratching my head so far, 5 seconds does not really tie up with
any xfs thread.
