    Hello sir,

    I've just cvsupped the new -C source, and installed a new kernel. My
    CD-RW could not be detected:

    Mounting root from ufs:/dev/ad0s2a

    (it's this ata1-slave thing).
    Previously, it has been seen as:

    acd1: CD-RW <CD-W540E> at ata1-slave UDMA33

    And everything worked fine, Teacs run in DMA mode without any problems.
    Another weird thing is that the first drive in atapicam mode (accessed as
    /dev/cd0, not /dev/acd0) reports "something" inside of it, while there's
    no CD inside (as you can see it in dmesg).

    After atacontrol detach/attach, I've got the thing flip-flopped:

    acd0: WARNING - removed from configuration
    (cd0:ata1:0:0:0): lost device
    (cd0:ata1:0:0:0): removing device entry
    ata1-master: FAILURE - ATA_IDENTIFY status=51<READY,DSC,ERROR>
    error=4<ABORTED>
    acd0: CDRW <CD-W540E> at ata1-slave UDMA33

    cd0: 33.000MB/s transfers
    cd0: cd present [879076549 x 1006698496 byte records]

    (the second drive is also empty)

    After some playing with atacontrol, it appears that it's rather random
    which drive gets detected. But I could not get them both working at one
    time, it always detected just one.

    Anyway, after some massive disk IO (installworld && mergemaster) and
    reboot, syncer decided to give up on one buffer. No idea, whether this
    is ATAng feature, yet it hasn't been happening on ATAold.

    greets,
