Comment 6 for bug 1648388

Lo:
1) To clarify https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1648388/comments/4 did you test 4.9-rc8 or 4.9?
2) Could you please boot into the default Ubuntu kernel (not upstream/mainline) and then execute the following command only once, as it will automatically gather debugging information, in a terminal:
