Ubuntu 13.04 Raring Ringtail was released just a few days ago and chances are you’re not running the latest Linux kernel just released today. This brief tutorial is going to show you how to upgrade your current kernel in Ubuntu to take advantage of some of the newest features in the new Linux kernel.

This release brings many changes including support for SSDs as hard-disk cache, improvement in the way jobs are shared among different processors, support for Radeon graphic driver, and many others.

The announcement by Linus Torvalds can be found @ http://lkml.indiana.edu/hypermail/linux/kernel/1304.3/02009.html

The Linux Kernel 3.9 is considered stable, which means it has been tested and proven to work although some systems might have issues with it. If you’re not confortable upgrading your kernel, please don’t do it. There’s almost no turning back when something goes wrong, so please backup your computer before attempting.

Below are some of the features of this kernel.

  • drivers: net: ethernet: cpsw: get slave VLAN id from slave node instead of cpsw node
  • netfilter: nf_ct_sip: don’t drop packets with offsets pointing outside the packet
  • ARM: 7699/1: sched_clock: Add more notrace to prevent recursion
  • ARM: cache: remove ARMv3 support code
  • ARM: mm: remove broken condition check for v4 flushing
  • bonding: in bond_mc_swap() bond’s mc addr list is walked without lock
