[Bug 930447] Re: Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M x86 Laptop due to bug in PAE kernel, initramfs or syslinux

[ImConfused]

My computer is PAE deficient.  Because of Linux Mint 13 Maya 32bit I am
able to use the Ubuntu XFCE 12.04 on my machine.   My machine was
originally designed for Windows XP.  Due to certain websites and a few
other reasons every once in a while I am foreced into Windows XP which
is a very painful experience.   I personally have found Ubuntu as an
operating system that keeps my old computer out of the landfill.  It has
better programs than Windows XP and it run circles around it as far as
what it can do under Windows.  Windows is necessary for certain
functions.  Some US Government websites are dependent on Windows.  Some
websites are totally designed around Internet Explorer.  If you want to
access those sites you have to have Windows on the computer.  Internet
Explorer under Linux isn't the greatest experience to deal with.  Also
being a much smaller piece of the computer pie Ubuntu is less attractive
for virus designers than Windows.  Canonical LTD is pushing non PAE
enabled computers off to the side by ending support for a sizable number
of computers that have not died a natural hardware death.  Making an
operating system that will only run well on the new computers  is a
Windows / Intel marketing game.  It the type of practice that should not
be adopted by Linux developers.  My 2 cents.

Title:
  Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M
  x86 Laptop due to bug in PAE kernel, initramfs or syslinux

Status in “linux” package in Ubuntu:
  Won't Fix
Status in “syslinux” package in Ubuntu:
  Confirmed
Status in Baltix GNU/Linux:
  Triaged

Bug description:
  Ubuntu 12.04 doesn't start from Desktop CD or USB with syslinux boot
  loader on Pentium M 1.6Ghz or faster Pentium M CPU - displays error
  message about missing PAE feature in CPU, but *the same* *Ubuntu
  12.04* Desktop CD/LiveUSB starts fine on *the same CPU* (and same PAE
  kernel) if GRUB boot loader is used, for example when WUBI or LiveUSB
  with GRUB boot loader, like Multisystem
  (http://liveusb.info/dotclear/index.php?pages/install ) is used!

  The error message is:
  "This kernel requires the following features not present on the CPU: pae.
  Unable to boot - please use a kernel appropriate for you CPU."

  THIS IS AN IMPORTANT REGRESSION! People are able to install and successfully use Ubuntu 12.04 on such pretty new hardware, like IBM Thinkpad T42 laptop with Pentium M 1700Mhz processor, but the bug in syslinux (or something related) forbids Ubuntu 12.04 installation.
  This bug is reproducible on lots of computers, there are several log files and /proc/cpuinfo file attached to this bugreport, AFAIK it's enough to reopen this bug.
