If you set debug.mpsafenet=0 in loader.conf, does the problem go away? We might be looking at a race condition in the task queue handoff for IFF_NEEDSGIANT. Another possible testing avenue (which might be slightly unstable but would illustrate the point) would be to leave debug.mpsafenet=1, disable preemption, and remove the IFF_NEEDSGIANT flag from the if_de driver flags.
