Hi, I'd the same problem on a DL 580. It seams to be a problem with the intel chips at the nics. the kernel took the e1000 for both cards, but their must be a differnce. after two days configuruing and testing, we take one card out of the system (didn't configure it) at build in a 3COM. Also supported by HP and running fine.

Recently I sent up a RHEL AS3 server on ProLiant ML370. It came with two network cards: one is NC7781 (shown in /proc/pci as Broadcom Corp NetXtreme BCM5703 Gigabit Ethernet) and another shown as PCI device 8086:1026 (Intel Corp) don't know what model, perhaps it's NC7131 or NC1020. By default I got the first one recognized by the OS automatically as eth0 and working fine. But when I tried to configure the second, I can't activate it as if I do so the first card would be deactivated and lost the connection. I suspected it as the driver problem, so I downloaded and installed the e1000 (suppose to be for NC7131) and bcm5700 (suppose to be for NC1020) driver directly from HP website (of course they are for RHEL AS3), and followed the instructions exactly. When I used Network configure wizard to add the eth1, the system captured the e1000 as the driver automatically no matter how I specify it manually. Once I activate the eth1, the whole connection thru eth0 got lost immediately. I have to goto the console manually deactivate eth1 and re-activate eth0 again should it be back to normal. Can anyone tell me what's going on here and how to get it resolved?
