Title:
  100% I/O usage due to jbd2

Status in “linux” package in Ubuntu:
  New

Bug description:
  
  I have 14.04 Beta 2 64-bit and Intel i7 Processor with 2.2Ghz clock, 4 GB RAM and 500 GB Harddrive.

  After using Ubuntu for some time, everything goes so slow and I cannot
  even move my USB mouse cursor, but only touchpad. Not possible to open
  even a terminal window.

  Here is the iotop output:

  http://pastebin.ubuntu.com/7227394/

  Also the cpu usage is around 3% only by chromium.

  I unmounted all ntfs disks (I even don't have sda8), but the problem
  is the same.
