I think the latest round of kernels might have broken this, I have 
similar issues with the latest updates for Fedora 10:
Dec 26 08:18:49 localhost kernel: end_request: I/O error, dev sr0, 
sector 0                                                    
Dec 26 08:18:49 localhost kernel: Buffer I/O error on device sr0, 
logical block 0
