Title:
  Ubuntu 12.04 completely freezes

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I'm using Ubuntu 12.04 64bit. At random times everything freezes,
  including the mouse and the keyboard. I cannot open any other ttys
  (Ctrl+Alt+F1-F6). My computer uses UEFI and so when I tried to run
  memtest86 I got the error message error: unknown command 'linux16',
  but I suspect that this is an unrelated issue to the freezing. I have
  sshd in to the computer and run "sudo cat /proc/kmsg", but no error
  messages appeared and the terminal froze - nothing happened when I
  pressed Ctrl+C.

  My computer has an Intel 15-3219M 2.5GHz CPU and 6GB RAM. I have an
  Intel HD Graphics 4000 integrated GPU. My computer is a Dell Inspiron
  and I also run Windows 8.

  Many thanks
