What about the boot option 'forcepae'? Is it still available, and possible to use in order to make Pentium M and Celeron M run a PAE kernel?
In that case, I think that it should be described in the wiki page that the error text is referring to https://help.ubuntu.com/community/EnablingPAE instead of (or at least alongside with) the reference to ugrading from 12.04 which is cumbersome and prone to failure. And is the tip about 'forcepae' still there in the error output? It is quite brief but will help people with some experience understand how to make the computer work. Others may need a more verbose help text (that I think should be in the wiki page). -o- I saw that you, Brian Murray, edited the wiki page March 3, so I don't want 'hijack' the page, instead I discuss here, what it could and should contain. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1160346 Title: do-release-upgrade from Ubuntu 12.04 on Pentium-M fails, breaks system without any warning (This kernel does not support a non-PAE CPU) Status in Ubuntu Release Upgrader: New Status in “linux” package in Ubuntu: Invalid Status in “ubuntu-release-upgrader” package in Ubuntu: Triaged Bug description: Attempting to upgrade from Precise with a non-PAE kernel will result in a failed upgrade. do-release-upgrade should check whether the user is using a non-PAE kernel and refuse to run, rather than upgrading to a broken system with no installed kernel.
