Would it be possible for you to test the latest upstream stable kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.4 stable kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Booting into 4.2.0-38-generic kernel seems to work fine. Up until this point 4.2 and four different 4.4 kernels functioned properly 90% of the time. Even then, roughly one-in-ten 'resumes from suspend' would panic, usually with blinking caps-lock LED. Cold- shutdown and restart would bring the system back up with little to no issue. This time was different, not sure why. Going through DebuggingKernelSuspend (https://wiki.ubuntu.com/DebuggingKernelSuspend) DID THIS: Shutting the lid of your laptop, which is set to suspend on close. DID THIS: Pressed the power button GOT THIS: kernel panic-- no blinking caps lock, just a single unblinking half-cursor at the top-left of the screen cat's of appropriate files are attached. If more is needed I am more than happy to oblige.
