9.2-RELEASE Kernel panic, mbuf underflow

[Shawn Wallbridge]

I tried building a kernel with INVARIANTS, but their is a known issue with INVARIANTS and 3Ware controllers..

http://www.freebsd.org/cgi/query-pr.cgi?pr=174684

I have built a new kernel with the fix mentioned in that PR, but I have to wait until EOD to boot into it.
