It did not introduce new SCSI commands (compared to prevuious versions) and I would be interested why this problem is discussed late. The only new thing with cdrecord-2.01a33 is that it started to transfer more than 4 bytes with the "read buffer" command. As this is only issued in case that the "read buffer" command did succeed with 4 bytes transfer count and as cdrecord does not transfer more than the drive advertizes, I am just depending on a kernel that does not freeze from the SCSI command I am issuing.
