[How To] Upgrade to Linux Kernel 4.0 RC6 on Ubuntu and Linux Mint

Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.




Linux provides users with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management.

Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.


What’s new in Linux Kernel 4.0 RC6:

• Things are calming down nicelly, and there are fixes all over. The NUMA balancing performance regression is fixed, and things are looking up again in general. There were a number of i915 issues and a KVM double-fault thing that meant that for a while there I was pretty sure that this would be a release that will go to rc8, but that may be
• unnecessary. Apart from the aforementioned issues, the bulk of this is mostly small misc driver fixes and architecture updates. The shortlog gives more of a flavor of what’s been going on.
