I think you may have the probe-all-LUNs set, and a CD burner which 
responds to more than one. That's one possible cause for this.

Unfortunately using ide-cd still doesn't have the code set to allow all 
burning features to work if you are not root. Even if you have 
read+write there's one command you need to do multi-session which is 
only allowed to root. Works fine for single sessions, I guess that's all 
someone uses.

Haven't tried unloading the module, so I have no advice on that other 
than "don't do that."
