I cannot tar /proc/acpi either. I presume this is because it's created only when ACPI is on and working.
I have tried disabling devices on my motherboard (Asus P8P67-M) in the hope it may have been a device issue, but cannot seem to narrow it down with that either. Got down to mouse + keyboard and that was it and was still getting this. As a side-note. I've never been able to get Ubuntu 12.04 to install as EFI with this board even though I can (but don't) with Windows 7 x64 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969955 Title: unable to boot without using acpi=off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/969955/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
