Title:
  kernel BUG at /build/buildd/linux-3.13.0/mm/slub.c:3365!

Status in linux package in Ubuntu:
  Expired

Bug description:
  Periodically (every few days) I'm hitting this kernel bug, which
  causes the session to close and drops me back to the login screen. If
  I attempt to login it does some stuff (usual screen flashes) then
  drops me back to the login.

  It seems to be when I'm doing something related to an item on the top
  Unity panel. I thought for a while it was when I was trying to
  activate Skype from the icon it places in the panel (so I assumed
  Skype was at fault). But I've just had it happen too when attempting
  to pick Sound Settings from the audio panel icon.

  I'll be happy to provide other information if I can.
