An easy way to test if the cdrw is triggering something weird.
Disconnect it for the next boot and see if the same thing occurs.  
If things stay the same, the cdrw is not the cause, but if they change 
then it would seem they are interacting.

You do not say if the cdrw is IDE or SCSI, but I suspect it is IDE or 
you would not be using ide-scsi.
