Here is the fix, which was posted in response to a seperate
report of this problem here:

commit c28728decc37fe52c8cdf48b3e0c0cf9b0c2fefb
Author: David S. Miller <davem@sunset.davemloft.net>
Date:   Wed Nov 29 18:14:47 2006 -0800

    [IPV6] NDISC: Calculate packet length correctly for allocation.
    
    MAX_HEADER does not include the ipv6 header length in it,
    so we need to add it in explicitly.
