You may want to use "make deb-pkg" instead.

Do you build kernels as root?  You really should not do this.

I have just built a 3.1 kernel from Linus' tree with make-kpkg, also in
a sticky directory, and it worked.  But I'm not building kernels (or
other Debian packages) as root.

Which kernel-package version do you use?
