Problem with Network Adapter

Hi everybody. I am new to Network programming, i need some help

I have 4 "Intel Corporation 82574L Gigabit Network Connection" ethernet adapters on sandy bridge system. I'm using Linux kernel 2.6.35.10. While i'm passing traffic from iperf software on any of ethX port and disconnect ethernet cable of ethX port i get "e1000e 0000:02:00.0: ethX: Reset adapter" message on my terminal. Also, in the dmesg i found these errors..

ACPI Error (dsfield-0143): [CAPB] Namespace lookup failure, AE_ALREADY_EXISTS
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0._OSC] (Node ffff88003f025710), AE_ALREADY_EXISTS
ACPI: Marking method _OSC as Serialized because of AE_ALREADY_EXISTS error


Please help me to know what the problem is??

Sorry to tell you, but you might not find what you're looking for here. This is more about network administration, not really network programming. You might get lucky though; I just wanted to give you a heads up that you might not get an answer for basically device driver programming here.

I'll ask some of our other mods if they think this better belongs in one of the misc. programming forums here where you'd have a better chance of getting an answer.

This is a crosspost from several other forum sites.

Does this typically happen when the network adapter is under heavy load?

Try booting with the pcie_aspm=off kernel parameter.

Moved to Linux Help.

I'll try to update my ethernet adapter drivers and see if the issue still exists.
When i type "lsmod" command i found 'e1000' module in the list. When i type "ethtool -i eth0" i found..

driver: e1000
version: 8.0.30-NAPI
firmware-version: N/A
bus-info: 0000:11:00.0

What's the difference between this module - e1000 and driver - e1000 ?
To update drivers, do i need to update even the module ?
Can someone help me ..

I told you how to make it work in my last post. Try booting with the pcie_aspm=off kernel parameter.
