| Thanks! Let me start by saying that I'm not asking for or expecting perfect hardware or software. This does not exist. I'm looking for improvements. Sane? Let's start with "sane-er". I linked to the i210 because it offers exactly what I'm asking for: improvement (as you'd expect in 4+ years of development). The link for the i210 was an overview for general consumption. The 862 page datasheet is here: http://www.intel.com/content/dam/www/public/us/en/documents/... The description of the various memory and configuration spaces starts around page 53. When compared to what's available in the 82574L this is clearly a substantial improvement. However, as I say in my update, we still don't /really/ know why this issue manifested the way it did. Without knowing the true underlying cause anything I offer is speculation, as are your suppositions. With that it is unknown as to whether or not the improvements in the i210 would have eliminated or even ameliorated this issue. As far as catching this exception in driver software? Possible, but doubtful. Working with Intel last fall they seemed to dismiss this possibility. Current drivers report a loss of communication with the PHY and the adapter seems to essentially disappear from the PCI bus until a full power cycle. Neither Intel nor my board vendor reported these findings to me until this story broke last week. I reported this issue to them last fall: both of them claimed to have never seen this issue before (or since). Meanwhile, as I’ve said before, other people have consistently reproduced this issue with different board manufacturers. We are pursuing a second source but I'm not going to be any more confident with the second source if it has 82574L controllers. I can't be certain it's going to be any different. |
