I am debugging a curious issue with the kernel not supporting my laptop completely. (This is my bug report)

I have installed the mainline builds from the mainline kernel ppa (http://kernel.ubuntu.com/~kernel-ppa/mainline/), and discovered that the last working kernel version is v3.2.1. Anything after it, i.e. v3.2.2, breaks. So I was going to use the git bisect tool to identity the specific commit between v3.2.1 and v3.2.2 which breaks on my laptop.

I followed the instructions but the git repo they link to doesn't have the tags for v3.2.x, so I found another one which sounds official and has the right tags: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary, but after building v3.2.1 I still had the issue.

So, what git repo do the mainline kernels come from?
Also, are any patches/changes applied to them after being retrieved from the repository which wouldn't be in my build?

The mainline builds are built from the official upstream repositories (linus's tree and gregkh's stable tree for instance). Where the build claims to be against a tag it is the official tag from that version. You can confirm you have the right one using the file COMMIT in the same directory as the binary .debs, this lists the SHA1 or tag which was used as a base for the build, all patches applied to the tree are in the same directory.
