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:
Fix Released
Status in “syslinux” package in Ubuntu:
Invalid
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.
