I want to go here https://code.launchpad.net/ubuntu/+source/linux and see how the kernel is packaged. Specifically I think there may be an old debian patch still in there that is affecting my hardware.
e.g. https://code.launchpad.net/ubuntu/+source/libevent shows the branches for the various releases and I can choose a branch and browse files.
How can I do this for the Linux Kernel?
