Nope. The 2.6.7 patch has to be applied to a vanilla 2.6.6 kernel. You'll have to download that from kernel.org. Most distros apply their own patches before distributing and these break upgrades to the main kernel tree.

Thank you for reply. So, If I have kernel 2.6.1 then I can patch it with patch file patch 2.6.7?
