>as Debian also includes a pae flags check in the 686 kernel package the pae flags check is in the x86 bootcode of the kernel and apparently it depends on the bootloader if it`s being executed or not.
only grub2 seems to skips that code which does vga initialization, cpu- checking and other steps like edd ( https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/x86/boot/edd.c?id=e479c8306f898fcdb9b36179071eae6338a17364 ) , which makes all the work pretty pointless. i wonder, why skipping that code is possible at all and nobody complains (besides that silent complain of hpa) for details, see https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/x86/boot/main.c (end of the file) and https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/x86/boot/cpu.c and https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/x86/boot/cpucheck.c btw - thanks Dimitrijs for the positive response. -- 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/syslinux/+bug/930447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
