    Cannot get the new kernel 2.6.0-test4 to boot


    I get this error message when I attempt to boot this kernel.

    VFS:Cannot open root device on "303" or unknown block(3,3)
    Please append a correct "root=" boot option
    Kernel Panic: VFS: Unable to mount root fs on unknown-block(3,3)

    I have searched google left and right and the only thing I found related to a problem that was fixed before test2 was released.

    I have tried seting root to /dev/hda3, and 0303.

    ---------Lilo.conf file ----------

    # LILO configuration file
    # generated by 'liloconfig'
    #
    # Start LILO global section
    #append="hdc=ide-scsi"

    boot = /dev/hda
    message = /boot/boot_message.txt
    prompt
    timeout = 120

    # Override dangerous defaults that rewrite the partition table:

    change-rules
    reset

    # VESA framebuffer console @ 1024x768x64k
    # vga = 791
    # Normal VGA console
    # vga = normal

    # Linux bootable partition config begins

    image = /boot/vmlinuz
    root = /dev/hda3
    label = Linux
    read-only

    image = /boot/2.6.0/bzImage
    root = /dev/hda3
    label = "Linux-2.6.0"
    read-only

    # Linux bootable partition config ends


    ------------End Lilo.conf File-------------

    Note: The kernel I'm trying to load is /boot/2.6.0/bzImage.

    here is my kernel configure file generated by gconfig (graphical configuration utility)

    Any suggestions?

    are you sure that root = /dev/hda3 is correct?
    try to run fdisk /dev/hda, and press "p" to see the partition table, or just check /etc/fstab to see where the root (/) partition is located.. i guess root partition will be /dev/hda1 or hda2..

    Did you compile IDE support into the kernel, or did you modularize it?
