Wodim stops during OPC and the kernel prints some messages: scsi: unknown opcode 0xe9 scsi: unknown opcode 0xed scsi: unknown opcode 0xf5 scsi: unknown opcode 0xeb If I burn as root, everything works fine. The used CD writer is a "PLEXTOR DVDR PX-712A 1.09". I've seen in the wodim/cdrecord sources that plextor drives are handled different from other drives. Do you know what the above listed commands are for? Maybe they could be included in blk_verify_command? If your'e not sure about the dangerousness maybe as a config option?
