brandon211, the next step is to fully reverse commit bisect from kernel
4.7-rc7 to 4.8.1 in order to identify the last bad commit, followed
immediately by the first good one. Once this good commit has been
identified, it may be reviewed for backporting. Could you please do this

Please note, finding adjacent kernel versions is not fully commit

Also, the kernel release names are irrelevant for the purposes of

It is most helpful that after the fix commit (not kernel version) has
been identified, you then mark this report Status Confirmed.

Thank you for your help.

  Ubuntu 16.04: system freezes instead of suspend after undocking

Status in linux package in Ubuntu:

Bug description:
  I'm using a Lenovo ThinkPad T450s. When the system was docked and then 
undocked, suspend won't work. Instead, the screen goes black, the system 
freezes and the fan runs on high speed.
  This problem persists with the (as of today) most recent kernel 
4.4.0-31-generic #50.
