Comment 102 for bug 930447

From what I understand Oliver is saying in #97, the problem is not that a non-pae kernel should be supportet, but that the LiveCD does prevent installation on boxes that run the -pae kerne just fine.

I've successfully installed and used the -pae enabled kernel on a ThinkPad R51, on which I receive the the error message about the the CPU not supporting PAE when running the LiveCD.
A clean installation was first carried out using the the non-pae mini.iso (http://archive.ubuntu.com/ubuntu/dists/precise/main/installer-i386/current/images/netboot/non-pae/mini.iso) to perform a network installation. After the installation and a full online-update was done, the PAE enabled kernel (linux-image-3.2.0-24-generic-pae_3.2.0-24.39_i386) was installed. A reboot and a the non-PAE kernel ( linux-image-3.2.0-24-generic_3.2.0-24.39_i386) was removed.

I've tried (like #96 suggested) to exchange the kernel and initrd in /casper on the LiveCD from USB (by startup-disk creator), with the working -pae kernel from harddisk. It bootet from the USB, but the error message about missing PAE capability was still thrown, why I believe it must be somthing in the squashfs image then.

So the conclusion must be, like that of that the #91, that there is a bug in the LiveCD image, that prevent it from running the PAE enabled kernel even on some PAE capable hardware.
