--- Comment #21 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
(In reply to Kristof Provost from comment #20)

Well, there is your problem.  In the old days we did use locks for exclusivity;
 that probably has changed on the interface lists, etc. with epoch().   Hence
are now having two operations running in parallel and not waiting for each
other.  At least that sounds very likely to me.   I can go and have a look in
about 2 weeks to debug and fix this.
