Comment 5 for bug 1072311

The Ubuntu Technical Board has decided not to support non-PAE in Quantal. because it is too much of a hassle to maintain (and they have to worry about new kernels for ARM and such). If that reason is not detailed enough, you should request more information in bug 897786, as the kernel devs are already subscribed to it. I agree that Fix Released status for Quantal is a bit confusing (should have been 'Won't Fix'), but nevertheless, the bottom line is that Canonical has decided there will be no non-PAE kernel for Quantal, and that this bug is a duplicate.
Any further inquiries should be made to bug 897786. Thanks.
