Also, some TCP implementations sometimes don't align the timestamp options in the headers as well. Also, as I mentioned, try IP over appletalk. Unaligned accesses are perfectly normal, _especially_ in the kernel. This is an axiom of the kernel networking decided a long time ago, and printing out a silly message when it happens doesn't make that any less true.
