swapon: /dev/dm-1 error early in boot process

[Jay Cliburn]

Early in the boot process -- so early as to not be found
in /var/log/dmesg immediately following bootup -- the following message
flies by on two rawhide systems (i386 and x86_64).  The x86_64 is
completely up to date; the i386 system is about 4 days behind.

The error message is:
Enabling swap partitions: swapon: /dev/dm-1: Device or resource busy

The i386 system has a single IDE drive arranged thusly:

On both systems, swap is eventually enabled properly, but what's up with
the error message?  And what are these invalid partition table messages
in the fdisk output?  /dev/dm-1 apparently corresponds
to /dev/VolGroup00/LogVol01, which is partitioned for swap on both
systems.

I've googled and searched bugzilla to no avail.  (I'm thinking of
changing my middle name to ZarroBoogs.)  Does anyone else see the swapon
error message?

Thanks,
