We still seem to have a problem with link training, which is why you are not seeing any monitor output. I'm hoping to get together with one of my colleagues today and use a DP protocol analyzer to see if we can figure out what is going on. There isn't a lot of visibility into the link training process from software, unfortunately.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
