Hi, Linked to from the Launchpad bug report
https://bugs.launchpad.net/bugs/930447 --- start quote --- Date Tue, 25 Feb 2014 13:01:47 +0700 From Chris Bainbridge <> Subject [PATCH] x86: set Pentium M as PAE capable Pentium M is PAE capable but does not indicate so in the CPUID response. This is an issue now that some distributions are no longer shipping non-PAE kernels (those distributions no longer boot on Pentium M). This small patch fixes the issue by forcing the PAE capability on Pentium M.
