Warning. The Linux kernel is a critical element of the system. To do the upgrade costs when one of your hardware devices is not working properly, and the new kernel may fix this problem. But at the same time installing a new kernel unnecessarily can lead to undesirable regressions, such as: no network connection, no sound or even the inability to boot the system, so install a new kernel on your own risk.
Linux Kernel 4.14 has a huge range of advanced drivers, hardware, settings, filesystems, performance tuning and much more.
