Austen, I believe that you are running the version of the diags with the Gigabit loopback bug.. v1.2.76. The first patch for this fix would have been in build v1.2D.77, as well as incorporated into v1.3.141 software. Please make sure you are compiling and flashing the latest diags and let us know if you are still having problems.

We at Tech are trying to debug some problems with our gigabit ports: they've seemed to stop working (sending and recv'ing) suddenly and there appears to be no reason for it. So, we decided to turn to the diagnositcs. We updated the diagnostics (b/c the old version has known gigabit problems) as per the release notes in SDK v1.3: we reinstalled the boot image boot1200.bin overwriting everything and installing Diagnostics v1.2.76. When we run the diagnostics, they fail on the gigabit tests; nothing is sent or received except in one case: if the first thing you do when you run the diagnostics is gigabit, internal loopback mode, run test continuously, then 16 packets are sent--after that nothing and if you go do something else (like an octal test or external loopback test) before you try this test, nothing happens. However, the octal tests work. Does anyone have any suggestions? Austen McDonald austen@cc.gatech.edu God does not care about our mathematical difficulties.
