Kernel command line does not correctly parse ip field if nfsroot

Bug description:
Kernel image linux-image-3.8.0.31-generic
Ubuntu 12.04.3 LTS
I'm setting up machines with nfsroot.
dhcp works fine, but a static address fails to set resolvconf.
The document
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
states that there are between one and nine fields in the kernel command line
option 'ip=' separated by colons.
The last two are dns0 and dns1
e.g.
APPEND root=/dev/nfs nfsroot=10.0.0.1:/exports/nfsroot initrd=boot/initrd.img
ip=10.0.0.200:10.0.0.1:10.0.0.1:255.0.0.0:itx1c:eth0:off:10.0.0.1:0.0.0.0
rootwait=1 nfsdebug=1 nfsrootdebug=1 rw
I find that if I supply one or both dns addresses, then the boot fails
with the message
ipconfig: too many options for eth0
and then when configure_networking (from scripts/functions in
/usr/share/initramsfs-tools/) runs (called by scripts/nfs) says it can't create
it's temp file
/tmp/net-eth0:off:10.0.0.1:0.0.0.0
After that we get a kernel panic as init completes badly.
Clearly the command line parsing does not meet the spec in the above
reference.
I'm sure I can work round this by not supplying dns addresses in the
command line and re-writing /etc/resolv.conf elsewhere, but this needs
fixing properly.
I'm not sure if the ip= line is parsed elsewhere so I don't have
enough information to offer a proper fix.
