Title:
  Linux Kernel acting weirdly

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Lately the booting has been troublesome. These are the things that are
  happening randomly when I select the above kernel:

  -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 overcome this by selecting the 3.13.0-54-generic kernel in Advanced
  options for Ubuntu.

  Update:

  I have installed 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 and I had to shift back to the *-54-generic kernel.
  The random part is getting skewed and the occurrence of the 2nd error is increasing.
