I see something like that all the time when there's a CD in the drive.
The auto-mounter attempts to read a file system from the disc, and can't
(e.g. because it's an audio disc), and those are the error responses
about the failure.  If it can read the disc (often, it takes a few
attempts, while the mechanics of reading a disc are run through; focus,
positioning the laser in the right spot..), or it completely aborts, the
error messages stop.

What type of CD is in your drive?

[tim at localhost ~]$ uname -r

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
