    You can try booting your server with knoppix ( http://www.knoppix.org ), and
    look for hidden files.
    
    If possible, do not allow Loadable module support , maybe this can avoid
    future problems with lkm.
    
    I am not sure if building a new kernel works. But if you have good results
    with that, tell me.
    
    Sorry about the porr English.
