dev 0b:00 probably refers to dev major=11, minor=0 (those were hex
values in the error message).  Find this by doing typing the following
command in a shell window:

    ls -l /dev | grep 11,	# Yes, the comma is pertinent!

Here's what I got:

    brw-rw-rw-   1 root     disk      11,   0 May  5  1998 scd0
    brw-rw-rw-   1 root     disk      11,   1 May  5  1998 scd1
    brw-rw-rw-   1 root     disk      11,   2 May  5  1998 scd2
    brw-rw-rw-   1 root     disk      11,   3 May  5  1998 scd3
    brw-rw-rw-   1 root     disk      11,   4 May  5  1998 scd4
    brw-rw-rw-   1 root     disk      11,   5 May  5  1998 scd5
    brw-rw-rw-   1 root     disk      11,   6 May  5  1998 scd6
    brw-rw-rw-   1 root     disk      11,   7 May  5  1998 scd7
                                      ^^   ^^
                                Major -+    |
                                Minor ------+


On my RH system dev 0b:00 is my first SCSI CD-ROM drive.  The blksize=,
blocknr=, sector, size= items pretty much confirms that it's a block
device, like a disk or a CD-ROM. 

Sorry, but I really can't tell you what's going wrong.  Maybe a CD was
mount'ed and somehow replaced before the old one was umount'ed???
