If, as root, you do something like:
        # cp /dev/fd0  /tmp/foo
without a floppy inserted, you'll see a single kernel messages in your logs:
        > <DATE/TIME> localhost kernel: end_request: I/O error, dev fd0, sector 0

So offhand, I'd say some program on your box is trying to read or write to the
floppy device.

If you have the psacct rpm (the process accounting package) installed, as root
you should be able to do:
        # lastcomm | grep "Jan 20 01:2"
to see the names of what programs were started between 01:20:20 and 01:29:59.
Somewhere in that output, probably around 01:22:20 or so, you should find
the offending program.

Thanks, Steve, but lastcomm returns nothing:

# lastcomm
