Oops when mounting cdrom

["Udo A. Steinberg" <sorisor@Hell.WH8.TU-Dresden.De>]

Hi all,

When mounting a 700 MB CD-RW in my Plextor CD-ROM, my machine
reliably oopses. Below is the first oops decoded.

Can someone explain to me what all those ksymoops warnings are
about?

-Udo.

ksymoops 2.3.5 on i686 2.4.0-test13-pre4.  Options used
