Your em1 is using MSI not MSIX and thus can't have multiple queues. I'm
not sure whats broken from what you show here. I will try to get the new
driver out shortly for you to try.
With this particular NIC, it will wedge under high load. I tried 2
different motherboards and chipsets the same behaviour.

There is a new revision of the em driver coming next week, its going thru some
stress pounding over the weekend, if no issues show up I'll put it into HEAD.
Yongari's changes in TX context handling which effects checksum and tso
are added. I've also decided that multiple queues in 82574 just are a source
of problems without a lot of benefit, so it still uses MSIX but with
only 3 vectors,
meaning it seperates TX and RX but has a single queue.
Thanks, looking forward to trying it out! With respect to the
multiple queues, I thought the driver already used just the one on
RELENG_8 ? If not, is there a way to force the existing driver to
use just the one queue ?
On the box that has the NIC locking up, it shows

ifconfig down/up just panics or locks up the box when its in this
state. I also have IPMI enabled on this nic, but it shows the same
issue with it disabled.
