XFCE mount issue?

[Thomas Schönhoff]

Hello,

very time I am running my ATAPI- CD (Panasonic CR-585) drive a 
"tail -f /var/log/messages" reveals an error I can't address:


  The failed "Get Configuration" packet command was:

Is this possibly a xfmount issue (of XFCE 3.8.16-1)?
My CD drive use to work fine, i.e. listening music, viewing docu 
CDs  or installing from....
So, I am stuck to find an error. First I thought of 
re-configuring the kernel but everything seems to be quite okay 
with this!
Now, what I'm really confused about is the "Error: illegal 
request" part of the above message!?

Does somebody have an idea how to manage this!?

Many thanks
