    I try to burn a cd which hw.ata.atapi_dma=1 but the same error is coming
    up. burncd died with hundreds of "burncd: ioctl(CDRIOCSETBLOCKSIZE):
    Device not configured". The following messages were printed to the

    console: ata1: resetting devices ..
    acd0: WARNING - removed from configuration
    acd1: WARNING - removed from configuration
    done
    ata1-slave: timeout sending command=a0
    ata1-slave: error issuing ATA PACKET command
    psmintr: delay too long; resetting byte count
    (cd0:ata1:0:0:0): lost device
    (cd0:ata1:0:0:0): removing device entry
    GEOM: destroy disk cd0 dp=0xc2e33e00

    any hints?

    best regards,

            Gordon
