dmesg |grep powernow [ 1.132134] [Firmware Bug]: powernow-k8: No compatible ACPI _PSS objects found. [ 1.132134] [Firmware Bug]: powernow-k8: First, make sure Cool'N'Quiet is enabled in the BIOS. [ 1.132134] [Firmware Bug]: powernow-k8: If that doesn't help, try upgrading your BIOS.
This is what I am getting when trying to upgrade from 14.04 to 16.04. I have been looking in many places but only found this old bug report that is in the same area. I have tried to boot 14.10 which works fine, than 15.04 which shows the same message but jumps past it and loads Ubuntu. So does 15.10. As soon as I try 16.04.2 The message is the last screen that is loaded. The machine then freezes and has to be rebooted. I hope I am not stuck with the older Ubuntu versions, since 8.04 everything just worked fine so I assume something in the ACPI polling has changed. I attached the output from dmidecode so that the configuration of the machine should be complete. Can anyone help, please? ** Attachment added: "dmidecode.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/398109/+attachment/4900381/+files/dmidecode.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/398109 Title: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands Status in linux package in Ubuntu: Invalid Bug description: Description: Ubuntu 9.04 Release: 9.04 cpufrequtils: Installed: 004-2 Candidate: 004-2 Version table: *** 004-2 0 500 http://us.archive.ubuntu.com jaunty/universe Packages 100 /var/lib/dpkg/status Expected: cpu freq scaling via cpu frequency scaling monitor applet Gnome Panel Found this: dmesg |grep powernow [ 4.230267] powernow-k8: Found 1 AMD Athlon(tm) Dual Core Processor 4850e processors (2 cpu cores) (version 2.20.00) [ 4.230287] [Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands.

I was trying to add the cpu frequency scaling monitor applet to my gnome desktop panel and I received the message: CPU frequency scaling unsupported You will not be able to modify the frequency of your machine. Your machine may be misconfigured or not have hardware support for CPU frequency scaling. My system monitor shows the percentage frequency each core is using just fine. My system is an Asus M2N68-VM motherboard w/ AMD 64 dual core 4850e 2.5 ghz processor The bios is AMI v 2.61 Hope this helps figure it out eventually. Thanks.
