I think this is essentially the same as the RHEL bug
https://bugzilla.redhat.com/show_bug.cgi?id=665601 that was fixed
earlier this year.

Title:
does not configure ipv6 vlan interfaces due to autoconf sysctl failure
Status in “ifupdown” package in Ubuntu:
Confirmed
Bug description:
upon upgrade to 11.10 the ipv6 vlan interface is not configured correctly, leaves it in a half configured state.
ipv4 configured properly, but not ipv6
#/etc/network/interfaces
iface eth0.83 inet static
address 192.168.83.2
netmask 255.255.255.0
iface eth0.83 inet6 static
autoconf 0
address 2002:XXXX:XXXX:53:XXX:XXXX:XXXX:XXXX
netmask 64
The failure is due to the sysctl calling net.ipv6.conf.eth0.83.autoconf = 0, which is incorrect since the dot is interpreted incorrectly, it should be
net.ipv6.conf.eth0/83.autoconf = 0
Fixed in 0.7~beta1
