Kernel 3.11.6: Upgrade your Kernel


The Linux kernel 3.11.6 is out and has brought a few changes and bug fixes along with it. Even if you don’t find any difficulties with your system, you might as well upgrade just to stay current.

Kernel 3.11.6

Most notable fixes in kernel 3.11.6:

  • drm/radeon: fix hw contexts for SUMO2 asics

Of course, if you’re curious and patient enough to read more about what other changes you can expect, we won’t stop you from looking further.

Installation of Kernel 3.11.6

The process lets you manually install the kernel on your Debian based system which includes Linux Mint and Ubuntu. The process is pretty fool-proof and two of our systems have successfully accepted its new kernel. However, we urge you to exercise reasonable precaution. Read it twice before starting. It’s all on you…

1. Launch the terminal

The best way is [Ctrl][T]. But you can go through the longer route if you like.

2. Enter the commands

The commands have to be entered in the terminal precisely, in the exact order one after the previous is complete.

Focus on the temporary folder

cd /tmp

Download the latest kernel

wget -O kernel-3.11.6

Install the downloaded kernel

chmod +x kernel-3.11.6

Set your system to use the kernel

sudo sh kernel-3.11.6

3. Restart your system

A quick reboot is going to start your system with the improvements brought forth in the release of kernel 3.11.6 and can be done however you’d like. If your terminal window is open – it always is on my system – you can enter the following command to do the same.

sudo reboot

Uninstallation of Kernel 3.11.6

Kernel 3.11.6 is a stable release and as such, shouldn’t cause any troubles to most systems. However, if you’re among the unlikely, facing more troubles than those solved, you can revert back to your previous kernel using the following command. Enter it in a terminal window.

sudo apt-get purge linux-image-3.11.6*

Restart immediately, unless for whatever reason you’ve chosen to live a nightmare.

And that’s it. Do let us know if you love it or hate it…

Kernel 3.11.3: Upgrade you Kernel


Linux Kernel 3.11.3 is out and it seems a perfect kernel update to upgrade to since Kernel 3.11 stable. It fixes quite a few annoyances and we’d recommend you get it just for the sake of being current out of everything else. Of course, kernels come out all the time so you might want to check out if you wish to have the latest kernel by visiting here from time to time.

kernel 3.11.3

The following are some of the most important fixes that comes with Linux Kernel 3.11.3.

  • rpc: fix huge kmalloc’s in gss-proxy
  • skge: fix broken driver
  • drm/radeon: fix panel scaling with eDP and LVDS bridges
  • drm/radeon/dpm: fix fallback for empty UVD clocks
  • tg3: Expand led off fix to include 5720
  • drm/radeon: fix handling of variable sized arrays for router objects
  • drm/radeon: fix resume on some rs4xx boards (v2)
  • drm/radeon: fix init ordering for r600+
  • drm/radeon: fix LCD record parsing
  • drm/ttm: fix the tt_populated check in ttm_tt_destroy()
  • drm/i915: fix wait_for_pending_flips vs gpu hang deadlock
  • rt2800: fix wrong TX power compensation

Of course, we have not much idea of what it means but if you are one of those who do, you might get more information from the change log.

Installation of Kernel 3.11.3

The process lets you manually install the kernel on your Debian based system which includes Linux Mint and Ubuntu. The process is relatively fool-proof and we ourselves have tried it on two of our systems. However we make no promises in case you screw it up. Read it twice before starting.

1. Open up the terminal

You can launch terminal whichever way you prefer. However, we really like [Ctrl][T].

2. Enter the commands

Again, do so at your own risk.

Set the terminal to focus on your download folder

cd /tmp

Download the latest kernel

Install the new kernel

chmod +x kernel-3.11.3

Set your system to use the kernel

sudo sh kernel-3.11.3

Yay! You’re done.

3. Restart your system

You can restart your computer whenever you’d like; not necessary to do it immediately. The changes will be apparent after a restart.

If you’d like to do it immediately, though, enter the following into the terminal.

sudo reboot

Removing the kernel 3.11.3

In rare cases, the kernel update might be more of a nuisance than help. In such scenario, you can remove the kernel from your system.

Enter the following command in a terminal window.

sudo apt-get purge linux-image-3.11.3*

A restart is customary.

Do leave us feedback. We’d like to know if it has been of help.
