Thanks for the reply.
 I am using and compiling kernel from kernel.org. I believe 3.18.27
with patches is as new as in January of this year. 

The 3.18 kernel was released in December of 2014, the .y patches on the
end of that release are for people who for some reason or another are
stuck with that kernel release, and are part of the longterm releases.

The overall kernel is over a year old, please upgrade.
