OK, the drive does not support the read buffer command, this is why cdrecord cannot do a DMA speed test. But you have a massive problem in the linux kernel that needs to be investigated. The test unit ready command _cannot_ return a "fatal" SCSI transport error as long as there is a drive connected. Please start with running the "scgcheck" command to get some informations on the compliance problems in your linux kernel.
