    Subject2.4 odd behaviour of ramdisk + cramfs

    I am experiencing a problem when I try to run the following script:

    #! /bin/sh
    cat /flash/modules-2.4.21 > /dev/ram1
    mount -t cramfs -o ro /dev/ram1 /lib/modules

    Running it once causes the mount to fail with 'cramfs: wrong magic' -
    running it twice will make mount succeed on the second try.

    Oddly enough, repeating the 2 lines within the script doesn't work either.

    The behaviour has been reproduced by several people with different 2.4
    kernels.

    As I need this to go into some boot scripts, I'd like this to work without
    human intervention.

    Any suggestions ?

    Typical kernel config:
    2.4.21 unpatched kernel tree
    CONFIG_BLK_DEV_RAM=y
    CONFIG_BLK_DEV_RAM_SIZE=4096
    CONFIG_BLK_DEV_INITRD=y
    CONFIG_CRAMFS=y
    CONFIG_TMPFS=y
    CONFIG_RAMFS=y
