Hi again I've managed to enter by booting into single mode. Here's the /var/log/dmesg from the amd64 knotcd3 kernel with parameters: single apic=verbose.

I hope this helps ** Attachment added: "/var/log/dmesg" http://librarian.launchpad.net/4317542/dmesg -- Can't boot: mp-bios bug timer not connected to io-acp https://launchpad.net/bugs/53910 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
