    SubjectProblematic CD-RW device (2.4.18, 2.4.19-pre8-ac5, maybe others)
    From
    Date

    Lately I upgraded my CD writer (a generic 6x4x32x) to a LiteOn
    LTR-32123S 32x12x40x.

    When I booted into the 2.4.18 kernel, which was configured with ide-scsi
    and its prerequisites, I got some strange error during the IDE
    autodetection stage:

    ...

    hdc: LITE-ON LTR-32123S, ATAPI CD/DVD-ROM drive
    hdc: set_drive_speed_status: status=0x51 { DriveReady SeekComplete Error
    }
    hdc: set_drive_speed_status: error=0x04
    ide1: Drive 0 didn't accept speed setting. Oh, well.

    The old cd-writer was working without any problems and was loaded as
    /dev/sr1.

    Recently I tried 2.4.19-pre8-ac5 and enabled ATA Works in Progress and
    enabled CONFIG_IDEDMA_NEWDRIVE_LISTINGS.

    The result: I get fewer of these errors, and the writer is loaded
    succesfully as /dev/sr1. Those messages still annoy me and I want to
    know if this device is known to be problematic and it not, is there a
    way to erradicate those messages at boot time?


    Thanks for your help/support.

    Later,
    Nicolas
