I went out and purchased a PCIe ethernet card - it uses the em driver. The system boots and it is em0.It works fine in 100Mb mode, but in gigabit mode, it does not pass any traffic although ifconfig reportsthe card as active and that it has negotiated 1000BTX full duplex.I have tried plugging both the igb and em cards into 2 different switches with the same result.
Hi, Try manually setting the card's speed to gigabit mode, instead of it auto-negotiating. Speaking from experience, I have known some cards to show either packet loss or just not work at all if the speed isn't nailed up when they are talking to some switches. -- J.
