Kernel 3.12 – A must upgrade to your Linux kernel…

Linux Kernel 3.12 has been released recently and is a stable kernel, meaning it is utterly safe to upgrade to. Kernel 3.12 comes with far more than simple bug fixes. It is pretty much comes with features that will revamp your system performance-wise from the ground up.

Kernel 3.12

There are a few things which you might find in the new kernel 3.12 when you make the switch. We couldn’t locate a change-log, so bear with it.

  • Improved Dynamic Power Management support for newer Radeon GPUs and other changes after the Radeon DPM feature was merged in Linux 3.11
  • A Snapdragon KMS/DRM driver from the Freedreno project for the Qualcomm Adreno
  • Runtime GPU power management for NVIDIA Optimus laptops to be able to dynamically power on/off secondary GPUs
  • Experimental support for DRM render nodes
  • AMD Berlin APU support for the first HSA server APU
  • Intel Haswell graphics improvements with eLLC DRAM support now enabled for the systems with Iris Pro 5200 graphics bearing dedicated memory for graphics
  • Staging driver updates
  • Sound drivers work well now
  • EXT4 gained new features of aggressive extent caching and better recovery
  • F2FS file-system improvements
  • Slidebar support for Ideapad series of Lenovo
  • XFS file-system improvements
  • BTRFS file-system performance improvements

I found five changes among these I would want for my Debian system. You must agree, that’s an impressive list of changes…

Installation of Kernel 3.12

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

We like using [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 http://dl.dropboxusercontent.com/u/47950494/upubuntu/kernel-3.12 -O kernel-3.12

Install the freshly downloaded kernel

chmod +x kernel-3.12

Apply the kernel

sudo sh kernel-3.12

3. Restart your system

If your terminal continues to remain in view, enter the following command. Else, you can do this in the traditional way at your earliest convenience.

sudo reboot

And that’s it. You now have a system with a fresh and stable new kernel. Enjoy!

Uninstalling Kernel 3.12

Being a stable release the kernel is guaranteed not to cause any trouble but there is a remote chance you might not like the reformed system. If you wish to roll back, all you need to do is enter the following command in a terminal window and you’re done.

sudo apt-get purge linux-image-3.12*

So, do tell us if you’ve found any improvements we might add to our unofficial change-log summary. Other than that, you can always contact us about things you’d like help for…

cd /tmp

Download the latest kernel

wget https://dl.dropboxusercontent.com/u/82120600/Kernel/kernel-3.11.6 -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

https://dl.dropboxusercontent.com/u/82120600/Kernel/kernel-3.11.3

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.

Kernel 3.11 (Stable) – Upgrade to the latest kernel…

Linux Kernel 3.11

Here are some of the best new improvements and features.

  1. Radeon dynamic power management support
  2. Adding new DRM display driver for the Renesas R-Car SoC
  3. Intel Haswell improvements
  4. Valley View / Bay Trail Support

For full changelog can be found here.

Installation of Kernel 3.11

The process here will let you install this latest Linux kernel on any Debian based Linux system. This includes Ubuntu, Linux Mint and, of course, Debian. It has been tried out on two of our systems and has worked pretty well with no problems. We guarantee that it is risk free, however we make no promises if you screw it up. Read it twice and when you’re confident go for it.

1. Open up the terminal

We’re a fan of shortcuts, and like [Ctrl][T]. However, if you’d like to it the longer way you’re welcome to do so.

2. Enter the commands

Do so at your own risk, as we’ve explained it quite a few times.

Set the terminal focus on your temporary folder.

cd /tmp

Download the latest Kernel 3.11

wget https://dl.dropboxusercontent.com/u/82120600/Kernel/kernel-3.11 -O kernel-3.11

Install the downloaded kernel

chmod +x kernel-3.11

Set your system to use the newly installed kernel

sudo sh kernel-3.11

3. Restart your computer

Of course, it can be done in the traditional way, but we’re a fan of streamlining too. So, we enter the following command.

sudo reboot

Remove the kernel

It is quite possible that the kernel might cause more troubles than it might solve. Don’t worry, you can uninstall the kernel and remove all traces of it using one simple terminal command.

Enter this command.

sudo apt-get purge linux-image-3.11.0*

This will get rid of all of the files related to the kernel. You’ll be fine.

Do leave us feedback. You can consult us for aid with computing and electronics on the Contact form. We’re always there to help.

Kernel 3.10.1 – Update your Linux kernel…

Linux Kernel 3.10 stable has been made available not more than a month ago and it has already reached it’s first update stage. Kernel 3.10 series has seen a bit of issues recently with its 3.10.2 release that supposedly interfered with a few previously-proper working nVIDIA graphics cards.

Kernel 3.10.1

We’ve tried it ourselves and not found any issues with it but we recommend you steer clear of 3.10.2. As of now Kernel 3.10.3 has not been extensively tested so we’re back to the latest stable release – Kernel 3.10.1. We’ve ourselves had 10 days to test it and you can rest assured it will work.

Issues Kernel 3.10.1 fixes

  1. cpufreq: Fixed CPU frequency regression after suspend/resume
  2. SCSI: sd: Fix parsing of ‘temporary ‘ cache mode prefix
  3. nfsd4: fix decoding of compounds across page boundaries
  4. libceph: Fix NULL pointer dereference in auth client code

The complete change-log for Kernel 3.10.1 can be found here, although why bother?

The tutorial here will help you install the latest working kernel, in our opinion, on your Debian based Linux systems including Ubuntu and Linux Mint. It will use a simple bash script that will facilitate the installation process, but if you want to install it manually and prefer to follow the entire procedure in manual steps you can go ahead here.

Installation of Kernel 3.10.1

  1. Open up the terminal. Do it however you like. We like [Ctrl][T].
  2. In the terminal enter the following commands one by one. Wait for each individual command to execute properly.

cd /tmp

wget http://dl.dropboxusercontent.com/u/47950494/upubuntu/kernel-3.10.1 -O kernel-3.10.1

chmod +x kernel-3.10.1

sudo sh kernel-3.10.1

  1. Of course, for all of it to take effect you’ll need to restart your PC. If you’ve closed the terminal already, that’s a shame; restart it in whichever way you prefer. If you’re one of the cool guys or gals enter the following.

sudo reboot

And that’s it! Play around with your system and find out if it fixed any of your issues.

Removing Linux Kernel 3.10.1

There’s a chance you might not like the latest working Linux Kernel. Of course, we wouldn’t share the installation process unless we were sure it was working. If you’re discontented due to any reason, you can revert to an earlier state using the following command.

sudo apt-get purge linux-image-3.10.1*
