--- Comment #11 from da_audioph...@yahoo.com 2009-03-30 20:24:43 --- I figured it out! I took a clue from my /var/log/dmesg [ 4.633657] [Firmware Bug]: BIOS needs update for CPU frequency support [ 4.633718] ACPI Error (psloop-0136): Found unknown opcode 20 at AML address ffff88012d27c633 offset 4F, ignoring [20080926] [ 4.633722] ACPI Error (psloop-0136): Found unknown opcode 6F at AML address ffff88012d27c638 offset 54, ignoring [20080926] [ 4.633726] ACPI Error (psloop-0136): Found unknown opcode 20 at AML address ffff88012d27c63c offset 58, ignoring [20080926] [ 4.633729] ACPI Error (psloop-0136): Found unknown opcode 6F at AML address ffff88012d27c640 offset 5C, ignoring [20080926] That line that reads, "Firmware Bug: BIOS needs update for CPU frequency support" was really bugging me. So I took a risk, d/l'ed the latest BIOS for my board, flashed, reset all my custom BIOS settings, and rebooted into my new kernel. I'm now able to use acpi-cpufreq and scaling works smoothly :) I think you can safely close this ticket and pass on the information to folks experiencing this same symptom: flash your BIOS! -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
