    Intel Gigabit ET Dual Port Server Adapter - Device stops rcv'ing packets on one port (100mbs) when connected with Catalyst 2950 switch (IOS 12.1(9) EA1)




      I am looking for some help on a tricky problem that is only occurring occasionally. I am getting random receiver hangs on PRO 1000 GE ports configured in 100Mbs / Full Duplex mode under Windows 2003 Server. Link stays up to the switch but device stops receiving packets at the server. It comes back to life after 30 or 40 minutes if we wait it out. Not sure if it would always start working again but on several occasions it has.


      Ports hang a couple times a day, more on some machines than others. I have 6 servers running in this solution. Two machines hang more often than the others. We have moved from the motherboard NICs to the Pro1000 NIC but that is also showing the problem and at about the same rate.


      The symptom is that the devices configured in 100Mbs / full duplex stop receiving packets. If I disable and enable the device under the Windows 2003 Server Control Panel / Network Connection Tool the device starts working again.


      We have been running the ProSet Drivers (Wx64 DRV - shp    200,800 10-17-2008 e1q51x64.sys) on other platforms without this issue. I know the drivers are older but I would like to solve the issue before I just start swapping out SW and/or HW.


      Traffic on the 100mbs link is very light. It is the control / management connection to the system.


      I have a high performance Supermicro Seaburg server platform that has four Intel devices. Two 82576EB on a Pro1000 PCI-E card and two 82575EB devices on the motherboard. Three devices are configured for 100mbs/full duplex and one (PCI-E Card) is 1Gbe.


      The 1Gbe port is running 300-600mbs rcv under constant load w/ a light xmit load.


      We have written a watchdog script to ping and reset the device when it stops for now.


      Does anyone know what is causing the 100Mbs device to stop receiving packets?


      I suspect it has something to do with the interrupt rcv ring processing or due to the high traffic on the 1Gbe link.


      Thanks in advance,
