Custom kernel 2.6.39 ubuntu amd64 packages optimized for core2 and above processors

The following are the dropbox links for the kernel 2.6.39 built by me optimized for core2 and above processors. This is 64 bit package.

I copied kernel source into /usr/src/ folder and built. This fixes the symlink problem in the built binary (earlier binary packages have symlink pointing to my home folder which is fixed by this build)

The packages are built with CORE2 processor with 300 HZ frequency. The packages have transparent hugepage support enabled.

    Can you please explain how did you fix the link problems? I am building custom kernels using your tutorials and test them in a virtual machine. Even if I use /usr/src/linux-xxx as a working directory, when i install the resulting packages in virtualbox, it always complain about some missing stuff. For example:
