Sorry, my testing environment is built on a embedded arm device. Changing
kernel version need lots of changes for device driver which is beyond my
ability.

I wish you could implement my configuration on your environment and test
if it's OK. After that, we can list the changes from 3.10 stable to 3.18
stable.

Thank you again~!
