    [PATCH] Avoid ide-scsi from starting DMA too soon · 2323c8a9

    This went into 2.4 with the following comments..
    
    ide-scsi driver starts DMA as soon as it writes the ATAPI PACKET command
    in command register and before sending the ATAPI command. This will
    cause problems on many drives. Right way to do it is to start DMA after
    sending the ATAPI command. I am attaching a patch that fixes this. This
    patch will allow many more CD-RW drives to work reliably in DMA mode
    than do today
