Custom 64 bit Ubuntu Kernel 3.1.1 optimized for i3, i5 and i7

Let me be terse

For building refer http://duopetalflower.blogspot.com/2011/10/custom-64-bit-ubuntu-kernel-31.html

Kernel 3.1.1 optimized with corei7 march, kernel frequency of 1000 HZ and processor selected as CORE2 (only built for 64 bit) with Ubuntu patches. The resulting deb binary are installable on ubuntu/mint systems

Kernel binary and buildscript zipped can be downloaded from the following mediafire link (

Buildscript can be downloaded from this mediafire link (whose sha256sum is 258c153288eb8a9a735e83a86e76cdfa7d2658eb75c6dc8b0a160bf4cc2f4fd9  buildscript-kernel3.1.1-i7.sh)

    You can download the tar.gz file with the kernel Uabuntu patches already applied! I used your instructions last night to compile kernel 3.2.0-12 optimized for core2 and everything stripped that didn't apply, and my bootchart time on kernel 3.0.0-13 Ubuntu 11.10 went from 43 seconds to 23.88seconds (I also stopped cups and bluetooth from auto-starting but that's it). Looking at the changelogs from day to day the changes are minor there so don't worry about rushing to recompile (At least until the power fixes finally get pushed)
