** Description changed: - I recently downloaded and built a live usb of the latest 12.04 daily - build iso for i386 hardware using the following link address: - http://cdimage.ubuntu.com/daily-live/current/precise-desktop-i386.iso. I - was not able to boot from the live usb due to the incompatibility of the - linux kernel on the 12.04 iso and my Pentium M laptop hardware. + 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 I received is as follows: "This kernel requires the - following features not present on the CPU: pae. Unable to boot - please - use a kernel appropriate for you CPU." I expected that I would be able - to install Ubuntu 12.04 on my IBM Thinkpad T42 laptop that has a Pentium - M processor, 1700Mhz processor. The root cause of the issue appears to - be that the default kernel bundled in the current daily build i386 iso - is the generic-pae kernel. It's my understanding that the generic-pae - kernel cannot be installed on cpu hardware that does not support pae. + 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." - I have been using Ubuntu since 10.10. I have been able to install 10.10, 11.04, and 11.10 on my Thinkpad without issue. My understanding of the December Tech Board kernel meeting is that the non-pae kernel will be supported until 12.10. If that's the case, there should be a version of the Ubuntu 12.04 iso available for download that can be loaded on non-pae hardware. - --- - AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + 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 - AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: debbie 9252 F.... pulseaudio - Card0.Amixer.info: - Card hw:0 'I82801DBICH4'/'Intel 82801DB-ICH4 with AD1981B at irq 11' - Mixer name : 'Analog Devices AD1981B' - Components : 'AC97a:41445374' - Controls : 26 - Simple ctrls : 18 - Card29.Amixer.info: - Card hw:29 'ThinkPadEC'/'ThinkPad Console Audio Control at EC reg 0x30, fw 1RHT71WW-3.04' - Mixer name : 'ThinkPad EC 1RHT71WW-3.04' - Components : '' - Controls : 2 - Simple ctrls : 1 - Card29.Amixer.values: - Simple mixer control 'Console',0 - Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum - Playback channels: Mono - Limits: Playback 0 - 14 - Mono: Playback 3 [21%] [on] CurrentDmesg: Error: command ['sh', '-c', 'dmesg | comm -13 --nocheck-order /var/log/dmesg -'] failed with exit code 1: comm: /var/log/dmesg: Permission denied - DistroRelease: Ubuntu 11.10 - InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) MachineType: IBM 2373PPU - Package: linux (not installed) - PccardctlIdent: - Socket 0: - no product info available - Socket 1: - no product info available - PccardctlStatus: - Socket 0: - no card - Socket 1: - no card - ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-15-generic root=UUID=8e82110c-928a-47f7-ba15-e767a29d933e ro quiet splash vt.handoff=7 - ProcVersionSignature: Ubuntu 3.0.0-15.26-generic 3.0.13 - Tags: oneiric running-unity - Uname: Linux 3.0.0-15-generic i686 - UpgradeStatus: Upgraded to oneiric on 2012-01-24 (18 days ago) - UserGroups: - 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
