    Default Lilo: strange warnings when scsi boot + ide-scsi emulation

    I am using Lilo to boot from a SCSI drive.

    My setup is as follows:
    sda: scsi main drive,
    Boot from MBR (/dev/sda),
    swap in /dev/sda1
    single partition in /dev/sda2
    no other partitions or OS
    hda: cdrom, handled by ide-scsi emulation
    hdc: dvd/cdrom, also handled by ide-scsi emulation
    no other drives!

    Now when I run Lilo it seems to work, but gives me a strange warning message:
    ide-scsi: hda: unsupported command in request queue (0)
    end_request: I/O error, dev 03:00 (hda), sector 6

    This is funny since I don't refer to /dev/hda in my lilo.conf file. I don't
    even have any IDE drives.


    Here is my lilo.conf file:

    disk=/dev/sda
    bios=0x80
    boot=/dev/sda
    map=/boot/map
    install=/boot/boot.b
    prompt
    timeout=50
    image=/boot/vmlinuz.2.4.21
    label=linux.2.4.21
    append="mem=1024M hda=ide-scsi hdc=ide-scsi"
    root=/dev/sda2
    read-only

    Supposedly the "bios=0x80" is telling Lilo to boot off the first drive, which
    is conveniently set by the motherboard BIOS. This works fine, but I
    am puzzled by the warning message. This did not occur with previous
    versions.

    By the way, I have compiled the kernel *without* IDE cdrom support and instead
    with ide-scsi emulation (as a module). Supposedly you run into problems
    if both IDE cdrom and ide-scsi emulation for cdrom are active at the same
    time.

    Thanks for any help!

    The warning is coming from the kernel when the latest version of LILO scans
    the drives in /proc/partitions. LILO only pays attention to drives with
    actual partitions, but I have seen complaints from a compact flash reader on
    USB, emulated as a SCSI device. The error report from the kernel does no
    harm.

    I, too, would love to know how to get rid of them.
