The report caused Intel shares to fall by over 9 percent, the biggest intraday drop in over two years. Sometimes they’ll work for weeks without a problem, other times they’ll hang up 20 times a day. It turns out that if the first packet received contains any value that I can find other than 1, 2, or 3 the interface becomes immune from any death packets where the value is 2 or 3. Dayton – I’ve updated my post to include two variations of the packet. However, I am wondering in integrated chips are not affected, and only add-on cards are? The time now is

Did you find the information on this site useful? After a lot of packet captures, Star2Star traced the problem to a particular VoIP manufacturer, and after further lengthy debugging the responsible packet was identified. Intel unveils next-gen Sunny Cove CPUs, graphics plans, and 3D silicon stacking After a tough year where it faced competition across all fronts from AMD, Intel hopes that the switch over to nanometer based chips and technologies such as 3D-stacking of logic The NIC crashing is appropriate behaviour in this case, though for them not having a watchdog is a pity.

Intel Authorized Distributors sell Intel processors in clearly 82574k boxes from Intel. That’s one of the first things Intel verified. Nice work, thank you for posting.


When I say the interface shutdown, well, remember my description of this issue – the interface went down. Alternatively, the Intel people in LKML can get indirect access to that information, all you need to do is to write a proper report to LKML with the results of this crowdsourcing effort.

Now, for the first time in months, we could shut down these ports on command with a single packet. This new hardware flew through performance and functionality testing. This specific part is no longer being manufactured or purchased and no inventory is available. Ow and following info: After a tough year where it faced competition across all fronts from AMD, Intel hopes that the switch over to nanometer based chips and technologies such as 3D-stacking of logic Intel has a fix, they just need to release it.

I’ve updated the post with a link to different versions of the packet and instructions on how to use them. I’m wondering now if this is a similar issue. The inetl port capture never saw the Trying hit the wire. This is how all redundant arrays operate, be it disk spindles, network cards, or even servers in a datacenter cluster.

I know how the OSI stack works. Do they have to be unicast? If you have any feedback or suggestions 882574l Ostinato, do drop by the mailing list! It hosed some VM’s from responding every couple of months.


You can see it all here. Thanks for all the careful tracking and detective work.

I’m having trouble believing that. Kielhofner’s team has been working with Intel on a fix for this bug, but as yet it is unclear how widespread the 82574, is or how other Intel hardware is affected.

Sorry I don’t have more to contribute to such inhel effort. The interface was dead until the machine was physically powered down and powered back on.
