Was wondering how I would go about installing Linux Kernel 3.0 with pae enabled in Natty? Is there a PPA available with this included or do I have to compile from scratch?
If you want to try directly installing the Oneiric kernel version, you can pull the .deb files you need from: https://launchpad.net/ubuntu/+source/linux
Otherwise, you can try automated daily builds of the current upstream kernels here: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ Though the -pae i386 kernel is not available here yet.
Go here and download it. Look at the bottom Download linux-image-3.0-1-generic-pae
