Hi;

It is my guess that you have mount the cdrom on another machine using nfs.
There is a bug in nfsd that gives the causes the symptoms you describe. The
fix is to umount the cdrom on the macjine upon whic it is mounted via nfs, 
stop "nfs" (nfs stop) on the machine with the cdrom, umount the cdrom on that
machine and start nfs again. This bug seemed to exist on all RH6.*
distributions.

Cheers
