Thanks a lot. I have removed it from the last line
of my /etc/modules. Now I can eject, mount, cdplay, etc.
my CDs.

However, I can't write to CD. I can write using kernel 2.4 but
when I boot with 2.6.11 and try that:


[EMAIL PROTECTED]:~/cdr-image$ cdrecord -v -dummy -eject  dev=/dev/hdc ~/cdr-image/cd.iso
cdrecord: No write mode specified.

One of my friends told me it may be related to these lines:

 Using libscg version 'ubuntu-0.8ubuntu1'.

So I tried to installed the latest version of cdrecord from the
usual, official, unstable Debian repository however apt-get tells
me that cdrecord is at its newest version.

How can I correct the situation? What modification (and how) should I
make to be able to write to CDs in 2.6.11?

Thanks in advance.
