ide-scsi + cdrecord = b0rked Reproducible: Always Steps to Reproduce: Actual Results: cdrecord bombs near end of CD burning with infinitely repeated scsi bus errors
ide-scsi is ridiculous in itself :) You should be using standard ATAPI burning now.
if your using 2.6.X, you shouldnt be using ide-scsi for an ATAPI burner. As you've found out, its broke, and isnt likely to be fixed any time soon.
