Title:
  Linux Kernel acting weirdly

Status in linux package in Ubuntu:
  Expired

Bug description:
  Lately the booting has been troublesome. 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.

  Updated BIOS, no change:
