    SubjectCannot boot after new Kernel Build
    Hi,
    I am trying to build a new kernel but what ever version 2.4.24, 2.6.0,
    2.6.1 i am trying to build I come across the same problem.

    when doing a "make install" i get the following error.

    /dev/mapper/control: open failed: No such file or directlry
    Is device-mapper driver missing from kernel?
    Comman failed.

    I have installed the lates packages
    device mapper 1.00.07
    initscripts 7.28.1
    modutils, lvm2.2.00.08
    mkinitrd-3.5.15.1-2

    If I just ignore the message and try to boot the machine with the new
    kernel then I get a Kernel Panic.

    VFS: Cannot open root device "LABEL=/" or unknown-block(0,0)
    Please append a correct "root=" boot option
    Kernel panic: VFS: Unapble to mount root fs on unknown-block(0,0).

    The boot command in grub is
    root (hd0,0)
    kernel /vmlinuz-2.6.1 ro root=LABEL=/ hdc=ide-scsi
    initrd /initrd-2.6.1.img

    It is basically the same (except the version) as I use for 2.4.20-28 so
    I assume the label is correct.

    I saw quite a few messages of similar type but no real answer to the
    problem. Any Ideas what it could be ? I am using RH9.0

    Thanks
    Alex
