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.
