[Manoj Iyer (manjo)]

I have applied the patch and built a kernel in PPA https://launchpad.net/~ubuntu-power-triage/+archive/ubuntu/lp1758264/

Open the ppa page: https://launchpad.net/~ubuntu-power-triage/+archive/ubuntu/lp1758264/

Click on Technical details about this PPA

This will show you the URLs to the flat PPA http://ppa.launchpad.net/ubuntu-power-triage/lp1758264/ubuntu/ from there you can download debs from the pool by hand, and transfer as needed.

This is true for most PPAs
