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:
apport-collect 1648388

===================================================
Then I edit /etc/sysctl.conf with follow commands and the system
don't hang while rebooting
vm.dirty_background_ratio=5
vm.dirty_ratio=10
kernel.panic=3
kernel.hung_task_panic=1
kernel.hung_task_timeout_secs=30
But I don't know if it's an appropriate fix or not.
Thanks
