Hey Michael, I'm not qualified to help solve this problem and can only help you ask the right questions (which is why I didn't respond to your response to my questions...). here's a link of interest: https://bugs.launchpad.net/ubuntu/+bug/122560 there is some interesting discussion of potential problems that might steer you in the right direction.
