saguti, the next step is to fully commit bisect from kernel 3.13 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your understanding.

None of the options for suspend are working. The process of suspend works fine but when the computer is waken, screen stays black and computer becomes unresponsive. Installation of packets such as uswsusp create a bigger problem as the computer freezes during boot process.
