If, after just moving the 3.14.9 to the 3.16.2-201 initramfs you had rebooted and did a "uname -r" you would have found that you were running the 3.14.9 kernel as that is what is in the initramfs.  You would have further found that if you plugged in a USB pen drive it would have failed since plugging in the drive would have triggered the install of the usb_storage module from the 3.16.2-201 kernel (from on disk) which is a mismatch.

Your action of rebuilding the 3.16.2-201 and 3.16.3.200 fixed that.

Happy all is well for you now.
