--- Comment #16 from Kristof Provost <kp@freebsd.org> ---
(Adding what was already discussed on IRC)
The above patch (or an alternative version where the ifnet is if_ref()ed be=
fore
the NET_EPOCH_EXIT()) does not fix the problem.

My current understanding is that this is because an ifp_detach() of an epair
will remove two interfaces, which can mean we're deleting one while it's be=
ing
moved to a different vnet.
