Devel Kernel Announcements

Our ubuntu-unstable repo remains based on the v4.4 kernel. We're still cleaning up some DKMS package before we move our official xenial kernel git repo over to track v4.4. We will then officially upload our first v4.4 based kernel to the archive for 16.04. We would like to aim for this to be available for widespread testing before the end of the month.
