Exact same behavior with 2.6.20-9.16. I've started a new thread on the mainboard manufacturer support forum for help / advice. I suspect this is a bios issue. URL to aforementionned thread: http://forum.abit-usa.com/showthread.php?t=121169.
Let me know if you need anything else (acpidump to check if the problem is in the bios or somewhere else ?) -- frequency scaling / detection broken on this box https://launchpad.net/bugs/85814 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
