No, I was not able to boot without acpi parameters on any amd64 release of Ubuntu (starting from Natty). But I would like to admit, that i386 kernels are booting without any acpi parameters on my machine (At least this was true for Natty). I can re-check with current i386 Live-CD if needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1072891 Title: Linux kernel requires acpi=noirq or acpi=off on Dell XPS 15z to boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072891/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
