Alas, still no joy. I updated to the latest development kernel and as previously. In EFI, system stops immediately after startup.
I am able to boot with the latest development kernal when system is in LEGACY mode. Additionally - I downloaded the latest daily build (9/21/2013) of Saucy. Tried to boot via usb stick in EFI, no joy, system stops immediately after the Ubuntu try it, install it screen. Editing startup options to acpi=off & "quiet splash" deleted, same thing, immediate stop after hitting F10 to continue with boot. System DOES boot Saucy flawlessly with system in LEGACY mode and the few tests I did it works fine. Thanks again! ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1129511 Title: Unable to boot system in EFI unless acpi=off & "quiet splash" deleted from grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1129511/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
