    Hi all

    I have made an initrd image for an embedded device. The image is packed with
    mkcramfs to one big image and everything runs great like expected.
    I can start X, fire up Firefox and so on. The image and Kernel
    are flashed to a Compact Flash Card( 64 MB) which is formatted ext2,
    and fires the system up by loading grub, and grub loads the kernel and
    initrd image.

    Then I have split up the big image in modules (root(busybox),X, icewm,
    firefox ...). I did this cause I would like to be able to update the
    modules on the fly, if e.g. a newer version / bug fix is released for the
    specific module. So, I copied all the modules to to Compact Flash Card
    and mounted them via loop during startup.

    The system start up fine, and all the modules are mounted like expected.

    Now the problem is, that when I want to start X, I get an Kernel oops.
    I tried to strace the call, but even the strace will oops.
    The only thing which is running is ash(the busybox default shell).

    I am running Kernel 2.6.8.1 and busybox is latest released (1.0).
    My next test would be to try a newer Kernel, but I am not that confident.
    If anyone has an idea, plase let me know.

    Thanks in advance and best regards.
    Anes
