Samuel Bushi, the next step is to fully reverse commit bisect from kernel 3.13 to 4.1 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.

These are the things that are happening randomly: -It boots up normally -It shows up a kernel panic saying that it tried to read/write outside of some hd(0) -Grub Menu might not even load and the notebook just beeps continuously. This occurs mostly when I restart after a Kernel-Panic-hang. -It restarts and I end up back at the grub menu. I tried installing linux-generic-lts-vivid. The first boot-up was OK but the pointer was missing (It was still there, but not visible). After that, the problem returned. The random part is getting skewed and the occurrence of the 2nd error is increasing.
