    If you empty the fifo and the drive fifo you burn a coaster. Thats a feature
    of CD burning and one reason I use 640Mb magneto opticals for testing CD
    stuff

    This one though doesnt look like the kernel, unless someone helpfully mangled
    a command

    Its a message from the drive politely requesting cd-record to talk valid
    commands. But as ide-scsi touches some commands (remapping old ones that are
    not supported on ATAPI) its possible to be kernel
