Bug closed upstream since 4.8 is EOL and the bug does not appear in 4.9 and 4.10. I'm willing to do a bisect to find the problematic commit, but only if I can get some guarantee that this will lead to someone taking the time to review the result and do what's needed to get a fix in 16.10. Otherwise I'm personally fine running a mainline kernel.

On 4.8.0-32-generic it works some of the time, but most of the time it freezes the machine. When the machine is frozen the screen is turned off, the power button light is on, but the machine does not respond to any input including the Magic SysRq keys, the only thing that can be done is powering off the machine by pressing the power button for 10 seconds. This happens both with suspend-to-ram and suspend-to-disk.
