Problem with memory stick

I have a Crucial 1GB USB 2.0 Gizmo memory stick. It does work, but not
without its problems.
When I insert it into the USB port, the kernel spits out a large number
of bad looking messages - I'll copy them below. /dev/da0 is created,
but no /dev/da0s1 is created. If I then do "mount_msdos /dev/da0 /mnt"
it gives an appropriate error message, but then /dev/da0s1 is
mysteriously created. At this point "mount_msdos /dev/da0s1 /mnt" works
just right, and it is ready to use.
I just get the feeling that it is not quite working how it should be. I
am using a fairly recent RELENG_6 (maybe two weeks old).
Here are the messages from dmesg.
