unresolved symbol

[Shoudong XU]

Hi,all.

    I'm running a Spruce board with NFS mode(load kernel image by tftp, then mount nfs as it's root file system), but When attempting to insert a module manually(/sbin/insmod xx.o), I get messages like:
    xx.o    unresolved symbol     unregister_chrdev
    xx.o    unresolved symbol     register_chrdev
    xx.o    unresolved symbol     __get_free_pages
    ...
    xx.o    unresolved symbol     printk

    And all those symbols are present in /boot/System.map, it seems this file is useless.

    Could you give me some advice?

Thanks

Shoudong
