Building a kernel with IPV6_MULTIPLE_TABLES=y breaks my IPv6 connectivity
quite badly.  It basically totally refuses to answer an IPv6 Neighbor Solicit
packet or IPv6 Echo Request packet.  I run a 'tcpdump -n ipv6', and I see the
requests come in, and no packets leaving.  Interestingly enough, if I try to
ping6 *out* of the box, it's totally willing to send a Neighbor Solicit outbound
(although it appears to totally ignore the Neighbor Advert packet that comes
back). Of course, things don't work very well at all with busticated Neighbor
Solicit.

A kernel built with IPV6_MULTIPLE_TABLES=n works just fine.

It should be fixed by this patch (already contained in net-2.6.19).
