    Hm, just a guess: do you have devfs mounted to /dev
    on the initial ramdisk (probably automounted by the
    kernel, with config option CONFIG_DEVFS_MOUNT=y)?

    Check the output of "mount", it'll show you if there's
    still something mounted under the "old" root.

    We use initrd + devfs for ages now (we even use romfs for
    initrd like you do), and it works fine with 2.4.21 too.

    HTH
