The kernel log says all!
I have 2 laptops showing the messages, both amd64.
One of them runs a 32-bit system in a VM with the linux-image-3.3.0-rc6-686-pae kernel,
that does not have this problem.
The amd64 kernel from unstable (3.2.0-2) does not show the messages.

The code that generates this warning (nla_parse()) has not changed
between 3.2 and 3.3-rc6, so this is probably due to a difference
elsewhere.  It seems to indicate a bug in the userland program sending
the message that is being parsed, but perhaps I misunderstand.

It would be useful if we could tell which program is sending the
message, but I think that may be difficult to do.

Life would be so much easier if we could look at the source code.
