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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/930447 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: Confirmed 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. --- ApportVersion: 1.23-0ubuntu4 Architecture: i386 CurrentDmesg: Error: command ['sh', '-c', 'dmesg | comm -13 --nocheck-order /var/log/dmesg -'] failed with exit code 1: comm: /var/log/dmesg: Permission denied MachineType: IBM 2373PPU dmi.bios.date: 06/18/2007 dmi.bios.vendor: IBM dmi.bios.version: 1RETDRWW (3.23 ) dmi.board.name: 2373PPU dmi.board.vendor: IBM dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: IBM dmi.chassis.version: Not Available dmi.modalias: dmi:bvnIBM:bvr1RETDRWW(3.23):bd06/18/2007:svnIBM:pn2373PPU:pvrThinkPadT42:rvnIBM:rn2373PPU:rvrNotAvailable:cvnIBM:ct10:cvrNotAvailable: dmi.product.name: 2373PPU dmi.product.version: ThinkPad T42 dmi.sys.vendor: IBM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
