Cross-posted at h-online.com:<p>I have a plurality of systems with <i>Intel</i> motherboards which demonstrate the same kind of problems. The motherboards in question have two Intel ethernet controllers, one of which is an 82574L.<p>The systems connect to two different networks. When the systems attach to one of the networks (but not the other) using the 82574L interface (but not the other), that interface dies after some unpredictable amount of time.<p>I have tried posting comments to the Intel engineer's blog post (and PM-ing the engineer directly), but they do not appear. In fact, there seem to be no comments at Intel's site, despite the post having nearly 6000 views (at my time of writing).<p>Something is not right here.
