Linux kernel 4.9 was officially unveiled more than two weeks ago, on December 11, 2016, by Linus Torvalds himself, and it brought many cool new features. We recommend reading our report if you want to familiarize yourself with its changes, but if you’ve dreamed of using it on Slackware 14.2 or its derivatives, now you can. Before attempting to install this custom build kernel based on Linux kernel 4.9, you should know that it’s compatible only with 64-bit systems. Also, you should keep in mind that your existing kernel will be replaced, and you need to make a backup of /boot/vmlinuz, as well as to change the GRUB bootloader configuration if needed.
