Upgrading Hardy kernel to Intrepid’s 2.6.27

Attempting to sort out a (minor?) ACPI power management suspend error I have seen some indication that an upgrade to the 2.6.27 kernel might be the solution.

How to do that?

Roll my own — nah. I want stability here. While I like building my own kernel, I am running Ubuntu on this laptop to avoid stability issues. Though, if I want to do it “The Ubuntu Way” this howto might be a good starting point. Also, Mariuz gives a good quick look at getting up to 2.6.28, though, now that kernel is a stable release so the patching may not be necessary.

For me, upgrading out of the Intrepid package tree seems like the best plan, but how does Ubuntu want to do that?

Made a passing attempt (I haven’t even taken my jacket off since getting home from work) at doing it through synaptic setting testing and backports in my repositories. This didn’t give me any newer kernel images (no surprise, really).

Found this nice one liner to handle the upgrade (gotta love bash).

# echo 'deb http://archive.ubuntu.com/ubuntu/ intrepid main restricted' | sudo tee /etc/apt/sources.list.d/intrepid-kernel.list && sudo apt-get update && sudo apt-get -y install linux linux-generic linux-headers-generic linux-image-generic linux-restricted-modules-generic linux-restricted-modules-common && sudo rm /etc/apt/sources.list.d/intrepid-kernel.list && sudo apt-get update

Mirroring the above here, in case the original site disappears.

This might also provide some insight into the finer points, though it is dated back a few releases.

Finally, Ben Collins of the Ubuntu Kernel team rolled a 2.6.27-rc3 kernel for Hardy. Thanks, Ben.

Putting this possible kernel fun off until I’ve had more time to sort out the suspend error and grok for any issues with 2.6.27 kernels in Hardy.
