--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
Yes, this is an unfortunate limitation of netdump.  At the moment there is =
not
much one can do other than to ensure that netdump uses an interface that is
mostly idle.  It may be possible to modify the driver to reserve a queue pa=
ir
for netdump so that we don't depend so much on consistent driver state - do=
 you
have any idea if that would be a straightforward change?
