Subject: Problem : Emulex card is losing the connection on the first of two
 10 Gb cards.


[1.] One line summary of the problem:
Lose network connection on the first network card (be2net driver)

[2.] Full description of the problem/report:
We have a emulux 10Gb (be2net) card in our HP Server. We are losing the connection on the first networkcard (p5p1) after boot. A simple ping to the server will work random, losing a few packages. If we ping from the server work it will work all the time. If we setup the next networkcard (p5p2) it will work all the time.

We have change the network card to a card from intel and the problem is gone.
