Luis? John? I applied the patch from johannes and it ended my issues atleast. I ran my machine for approx 2 hours without seeing the disconnect issue (which I usually saw after 15-25min). Cant be 100% of course but so far so good. I agree with Justin that we could wait until he gets a chance to test it. It should be accepted after initial merge (and stable trees) after that I think. Rafael thoughts? Also, we should notify the atheros people so they could start fixing the driver (in a perfect world).
