Title:
  Kernel BUG: unable to handle kernel paging request at ffffffffa03ff521

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Just after reboot with a new kernel, I saw a Kernel Oops/BUG scroll up
  the screen.  light dm didn't load properly (I saw the mouse overlaid
  over the kernel Oops text instead of the user picker) and Ctrl-Alt-F1
  made the mouse disappear but didn't give me a console so I had to do a
  hard reboot.   The computer then booted successfully.

  I've attached the dmesg output from the failed bootup since I'm not
  sure if it reproduced in the current boot dmesg.

  I've seen the mouse-over-text problem before but I thought it was
  resolved after upgrade to Raring (tracked by Bug 1094567).

  I'm running a Samsung NP900X4C-A03US laptop.
