apport information

** Tags added: apport-collected staging trusty

** Description changed:

  This is an upgrade of LXLE (lxle.net) from 12.04 to 14.04.
  The installation has been done by leaving the /home partition intact and installing the 14.04 upon the re-formatted /boot and /root and /swap partitions. The size of all the partitions have been kept the same.
  
  I get this error soon after I start up the Notebook pretty much 70% of
  the times. And it comes up multiple times while the Notebook is on. What
  follows are random spikes of CPU load with few seconds of freezes.
  
  However, when I use Chromium, thing get worst. CPU spikes are longer and
  it often requires a restart.
