Packet loss on Intel 82579LM Gigabit Ethernet Controller

Post by daleng »

We are experiencing packet loss when we use the Intel 82579LM ethernet controller on the Intense-PC. A little googling on the subject quickly reveals that this is an issue with this particular controller from Intel.

http://communities.intel.com/thread/32022

Intel describes this issue in Erratum 23 in this document: http://www.intel.com/content/www/us/en/ ... pdate.html.
Problem: Systems with Intel 6 Series Chipset and Intel C200 Series Chipset using the Intel
82579 Gigabit Ethernet Controller may experience packet Loss at 100 Mbps and 1 Gbps
speeds when the link between the Intel 82579 Gigabit Ethernet Controller and the PCH
Integrated LAN Controller is exiting the Low Power Link (K1) State.
Implication: Implications are application and Internet Protocol dependent.
Workaround: A BIOS code change has been identified and may be implemented as a workaround for
this erratum.
Status: No Plan to Fix.
This issue prevents us from using this ethernet controller, and we might be prevented from using the Realtek 8111 one for our application.

Is there any chance that the mention BIOS workaround can be released in an updated BIOS for the Intense-PC?

Any update on this issue?

We are trying to solve an issue with Intense PC Core i7 Multi LAN and this could very well be related to the mentioned issue. Has this been solved?
