[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
There were *very* strong signals that the board, deciding about the
main-stream ubuntu edition, had decided to stop supporting non-pae CPUs
including Pentium M amd Celeron M, and that the decision was not going
to be changed.
You think that fake-PAE has been counter-productive, that it has done
more harm than good. Maybe you are right, maybe not. I still think it
was right to offer it as a solution to users, who would otherwise not
use these computers with modern Ubuntu based versions (because I thought
that the decision was not going to be changed). However, I'm hoping it
will change now, that there will be Trusty kernels, that can be booted
and upgraded with Pentium M amd Celeron M.
I can understand that you and many other people do not trust minor
distros or the organisations behind them or community re-spins. But who
can we trust? I think the [big] companies are at least as likely to
create and hide back-doors for themselves or some national intelligence
service organisation.

Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M

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.
