Mats, the bug you describe is a different one. This one is about frequency scaling being not supported, while your output states 5 supported frequency steps.
I've solved the problem on my Asus P5B-E motherboard but upgrading to the latest BIOS. It still persists with the Quadcore and Atom machines that I've tested. Since quite a few people seem to be able to solve this via BIOS up- or downgrades, it seems Linux / Ubuntu is not the one to blame. -- cpu frequency scaling not supported after upgrading to 9.04 https://bugs.launchpad.net/bugs/365798 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
