--- Comment #1 from Andrey V. Elsukov <ae@FreeBSD.org> ---
Looking to the call trace, it seems impossible. I think someone has modified
the memory, where mbuf is placed before it comes to m_copydata. We had such
strange panics (they are not related to IPSec) with 9.x-STABLE and 40G cxgbe(4)
cards. The traces also shows NULL pointers or in some cases mbufs with
incorrect content in places, where this looks impossible.
