    Hi,
    
    I do not have a /proc/ksyms but I tried the command with the System.map 
    from /boot.  I also tried the command with /proc/kallsyms (if that is the 
    same thing?).  There was no output from running the command on either of 
    the above.
    
    I am using 0.4.0.  Should I be using a beta?  If so, where can I get them?
    
    Thanks,
    Richard
