I do not get this warning for any of the kernels I build, whether from Linus' tree or Josh Boyer's Fedora tree. It shows up when I test kernels built by Fedora, but those don't have your debug patch.
I do not know what is different. Do you have any ideas? Most likely I won't be able to test any more kernels until Monday (unless I can use most of my most recent build over again very soon).
