** Attachment added: "/var/log/syslog from Ubuntu 12.04 live CD started with GRUB on system with Pentium M (no PAE)" https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/930447/+attachment/3176574/+files/syslog.gz
** Summary changed: - Unable to Install Ubuntu 12.04 on Pentium M x86 Laptop due to bug in PAE kernel, initramfs or syslinux + 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 ** Description changed: 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. - My understanding of the December Tech Board kernel meeting is that the non-pae kernel will be supported until 12.10. --- 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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
