There are three possible culprits in your system: the floppy driver, the IDE disk driver and the IDE CD driver. Which one were you using when the devstat messages appeared? Whichever one it was, someone who understands it (Mike?) should probably take a look at the driver and see whether we're getting transactions completed twice, or transactions that get completed, but were never started.
