    SubjectPROBLEM: (libata) cdrom drive not detected in -mm series
    Hi!

    My USB CD-ROM drive (that is detected as a SCSI drive) is not being
    detected on the -mm series of the Kernel.

    With a 2.6.18-rc6-mm1 tree and after some bisection work, I've found
    that the problem is somewhere on these patches:

    git-libata-all.patch
    libata-ignore-cfa-signature-while-sanity-checking-an-atapi-device.patch
    kerneldoc-error-on-ata_piixc.patch
    libata-add-40pin-short-cable-support-honour-drive.patch
    libata-add-40pin-short-cable-support-honour-drive-fix.patch
    asus-mv-device-ids.patch
    1-of-2-jmicron-driver.patch
    1-of-2-jmicron-driver-fix.patch
    2-of-2-jmicron-driver-plumbing-and-quirk.patch
    2-of-2-jmicron-driver-plumbing-and-quirk-cleanup.patch
    non-libata-driver-for-jmicron-devices.patch
    via-pata-controller-xfer-fixes.patch
    via-pata-controller-xfer-fixes-fix.patch
    via-sata-oops-on-init.patch
    libata_resume_fix.patch

    Doing a "quilt push
    fail-kernel-compilation-in-case-of-unresolved-symbols-v2" (that is the
    patch right before the ones from libata), I get a working Kernel, that
    detects perfectly my CD-ROM drive.
    With a "quilt push libata_resume_fix" (so all the libata changes get
    included), the resulting Kernel doesn't detect my CD-ROM drive.

    With the libata things applied I can see on /proc/devices:

    (...)
    Block devices:
    7 loop
    8 sd
    11 sr

    But even with sr_mod loaded, I can't get any /dev/sr0 or /dev/scd0.
    Since udev is the same with all the tests and /dev/scd0 is there
    without libata updates applied, I think that it's something not with
    udev, but with the Kernel.

    I am sending attached a diff file against dmseg of a working
    2.6.18-rc6 against a non-working 2.6.18-rc6-mm1 and also the config
    file that I am using with 2.6.18-rc6-mm1

    Please, CC me with any answers, questions, etc.

    Thank you very much!

    Best regards,
    Nelson
