Kirill Bogdanenko, thank you for your comments. Regarding them https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072891/comments/5 : ?"> Despite this, were you able to boot without the parameters in a release prior to Quantal? No, I was not able to boot without acpi parameters on any amd64 release of Ubuntu (starting from Natty)."
Could you please test for this in a amd64 Lucid live environment via http://releases.ubuntu.com/lucid/ ? >"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." It would be helpful to know if Quantal i386 does not exhibit the same behavior. Could you please check this via http://releases.ubuntu.com/quantal/ ?
