I am unclear how to perform the requested test and it seems some docs need updating.
I read the instructions provided but am not clear exactly how to perform the requested test with a mainline kernel. I also haven't had time to do this test until now so the versions you might want tested have probably changed. I read https://help.launchpad.net/Packaging/PPA/InstallingSoftware but wasn't clear if just running "sudo apt-add-repository ppa:kernel-ppa/ppa" was enough. Adding the ppa it gave a warning: You are about to add the following PPA to your system: Ubuntu Kernel Team Daily Build PPA - this PPA typically contains experimental packages. The quality of these packages is such that you had better know what you're doing. Don't come crying to the kernel team if it kills all of your kittens. More info: https://launchpad.net/~kernel-ppa/+archive/ppa The information at that URL talks about Lucid, not Precise. running apt-get update now gives these errors which leads me to believe more is required somewhere.
