RE: Intel® 82574L Gigabit Ethernet Controller Statement

Since we start with a preconfigured HD image, we were actually using an earlier driver to start with. We thought that to be the problem when it was first discovered. However, a change to the driver posted around Q1 '13 time frame did not resolve the issue.

Interestingly, as Wayne pointed out, one of our IT Guru's had also experienced this issue with POS terminals and had taken the same route with disabling the power management settings as well as Flow control and TCP/IP offloading features. However, in our situation we have yet to find that magic setting that eliminates the problem.

Needless to say, all of the fuss is FAR more than I would expect for a setup such as ours (based on history). Since the downtime costs more than Gold plated cards, I am opting for a different card at the moment and will keep one of the errant machines to play with back at the office. I am still interested in a fix as I have most of these cards remaining in stock.

Thanks.

Mark,

With the testing we have done on Windows 7, I think I can say confidently that it's not a driver problem, not a windows problem but a problem specific to the 82574L chip introduced some time after a 12/2011 manufacture date. We have swapped what should be identical cards between two systems one with 12/2011 manuf date and one with 12/2012 manuf date and the problem follows the card every time. We have also moved the streaming on a system with two NIC's one 82547L and the other an LM chip I think, and the problem only shows up o the 82574L NIC.

Thanks for the additional information. I see you are running Windows 7, not XP like Phil. So this isn't just an issue with XP. Sorry you had to replace the cards.

Hi Wayne,

Are you guys running Windows XP PRO with SP3? That was the OS Phil reported. If we narrow this down to a particular OS (or not) that will be helpful information.

A newer driver was just posted at http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=18717

I don't know of a specific driver change that might resolve this issue, but it is probably worth a try.

Another possibility is that there might have been a driver change in the newer drivers and that an older version of the driver might work better for Windows XP for your particular application. I spotted a version of the driver from March 2012 at https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21942

Maybe the older driver will actually work better.

Thanks for the information.

Phil,

Are your computers running Windows? We have found in Windows 7 if you disable Link State Power Management (in power settings, advanced, PCI Express) it should work much better. If you're not running Windows, try finding ASPM (Active State Power Management) in the BIOS and disable that.

IMHO, cards are still 'broken', we have about 800 in the field and have qualified another and are actively replacing them. We have pinned it down to cards (or motherboards) with 82574L chip of post 12/2011 manufacture.

Our use of the card is for a machine LAN (hardware separation from plant LAN) utilizing Ethernet/IP protocol. In this configuration we are physically connected to a Hirschmann Spider 5tx and then to a managed RS20-16 through Shielded Ethernet cables. There is no POE involved. The PC hosts the HMI software (RSView32) that sits on top of an industrial machine control monitoring about 3000 tags of information from the PLC and drives that are connected to the RS20. We are utilizing Rockwell OPC and Eurotherm OPC to serve upthe data to the HMI program.

We currently have over 40 instances of this same application (software/hardware/versioning) with failure only occurring in the lines with the previously described NIC card. Since it is random, from daily to every several days, it has been difficult to pin down causes or conditions. I do not have the luxury of in-depth lab testing so we may be forced to pull the cards and go to another type.

Thanks Patrick - I like your mobile phone example, especially given the number of active cell phones is forecasted to reach 7.3 billion by next year, which will be more than the entire world population . For folks that have an iPhone, Apple offers their iCloud service to store "all the stuff you can’t live without".

Thanks again for your feedback.

The best to explain the Cloud to non experts ; is to take a practical example of an application of the cloud that could help them directly

The easiest and best example for me is the mobile phone that we all have now and depend so much ; many are broken ; many stolen ; and there are so much bugs of all sorts ; how many persons do backups? Can do restore in few hours ; probably below 1%

Then you ask them the question ; if somebody steal your phone ; it is important ? most will say YES ; they have plenty phone numbers ; photographies that have huge emotional value etc

But they have no backup ; then now you can explain a potential application running in the cloud that could save their life

Let's imagine a service that backup you phone transparently ; and restore it in minutes on another phone or tablet thru a virtual phone at any moment ; whatever the source of the crash etc ; and would cost almost nothing ; would you take that application?

They respond YES?

But where are the data?

IN THE CLOUD

can be few km away or on another continent ; you dont care ; will not be on a single site in fact

You care that for a microscopic cost you can recover all your precious data at any time whatever the reason you need to recover ?

Now they understand the cloud ; they dont need more ; they are consumers

You need naturally explain that the data are well protected ; encrypted etc that nobody can read it or exploit it : OOPS this is not the case :-)

And why this is not part of the initial purchase of the phone; why should we buy this service?

And who will audit that I am protected ; from all sorts of predators?

And if the company X die ; can I recover my data

The cloud open lot of questions for experts?

There are solutions naturally; but this is much more than just engineering; dont say that to your parents :-)

Thanks for the feedback but I question your bottoms up estimates. National statistics place 35% of all care spent is on ambulatory care services (and yes much of it is driven by chronic disease). About 4% is on ED services and a recent study from Truven

Mark,

While we are using IP cameras in our testing, They are on another switch, so the one the computers are on now is a vanilla NetGear switch (no PoE), but we've had other switches in play as well with no difference. For us, cards of date 12/2011 made in Malaysia work fine, cards of 12/2012 do not (100% failure in the lab over 10-12 cards) . We are using both Dell systems (OptiPlex 790 and 990) and the Intel DQ77MK motherboard. As Phil states, the non 82574L NIC's all work fine, no failures, but as a separate card or on the motherboard, the 82574L chip fails, all the time.

I do believe streaming video is part (or all) of the cause.
