pramathesh ambasta, the next step is to fully reverse commit bisect from kernel 3.16 to 4.0 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

I had started backintime-gnome to take a backup of my home directory on an external seagate drive connected to a 4 port USB hub. This is something I do almost daily I was editing a desktop shortcut on nano when suddenly I saw a black screen with a lot of dumps and messages from the kernel (or what seemed like the kernel). The screen was frozen - no mouse movement or keyboard movement would restore it. I had to force a restart using the power button. This is the first time I have encountered something like this.
