CPU warning message

I am using Ubuntu 15.04 with Dell Inspiron 1525 laptop and recently observed that my system is working very slow. After checking my dmesg command it is showing some warning messages from CPU. Also dmesg is not producing the output since the ubuntu boots and it is showing the output for some particular period. I am providing the dmesg output below for your reference.
