I've added a comment with a few details on the matter at http://forums.lenovo.com/t5/Linux-Discussion/S10-2-Wrong-Clockspeed-ACPI-Table-Error/m-p/175100#M1616.
You may want to try the same techniques to isolate the problem and make it a stronger case for Acer support.

I suggest closing it with an appropriate status. -- Atom N280 frequency scaling not supported https://bugs.launchpad.net/bugs/422858 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
