Include(KernelTeamHeader)

Welcome to the KernelTeam FAQ! The aim of this page is to provide an up to date list of common questions that we get. We encourage you to update this document when something is missing so it becomes a core source of information for the project.

General Questions

Can I get a patch included in Ubuntu's kernel?

See KernelPatches.

The Ubuntu kernel config produces huge packages

Our build includes CONFIG_DEBUG_INFO in order to produce linux-debug-image packages. We then manually strip the modules after build.

If you re-use our config for your own build, your best bet is to change this line in the config:

CONFIG_DEBUG_INFO=y

To this:

# CONFIG_DEBUG_INFO is not set

I get dm-linear errors upgrading to gutsy

We've removed a long time patch to our kernel to work around problems in evms. This patch creates more issues than it "fixes". Please see this FAQ for work arounds: http://evms.sourceforge.net/install/kernel.html#bdclaim

Here is a list of patches applied to the Gutsy kernel that are not maintained upstream.
