[Bug 398109] Re: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands
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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/398109 Title: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/398109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@swordfish: Option 2 is the way to go, that warning about the 8254 timer can be safely ignored. Your BIOS does not provide ACPI _PSS objects in a way that Linux understands almost always means that Cool 'n Quiet has been disabled in the BIOS. This kernel message also isn't really an error, it just tells that the kernel will not use CPUFREQ powernow-k8 support because Cool 'n Quiet has been disabled, so it's doing exactly what is requested. Unfortunately the Ubuntu people chose to built-in the powernow-k8 module, so there's no way to prevent powernow-k8 from being loaded, what may be exactly what you want... ** Changed in: linux (Ubuntu) Status: Incomplete = Invalid -- powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands https://bugs.launchpad.net/bugs/398109 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

Hi NeilEvanJensen, This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 398109 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.] ** Tags added: needs-kernel-logs ** Tags added: needs-upstream-testing ** Tags added: kj-triage ** Changed in: linux (Ubuntu) Status: New = Incomplete -- powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands https://bugs.launchpad.net/bugs/398109 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

Hey all... I was a little busy last time, but I found solution ;) I've got Asus M2N-MX SE Plus mainboard. Usermanual you can find here: http://support.asus.com/download/download.aspx?SLanguage=en-usmodel=M2N-MX%20SE%20Plus BIOS version is v02.58 1958-2007 American Megartends inc. Kernel is 2.6.28-14.47 1) Default BIOS settings : * Cool'n'Qulet - disabled * ACPI APIC support - enabled * MCP61 ACPI HPET TABLE - enabled Error is: MP-BIOS bug: 8254 timer not connected to IO-APIC Log file is: dmesg1 2) Settings A: + Cool'n'Qulet - enabled (changed) * ACPI APIC support - enabled * MCP61 ACPI HPET TABLE - enabled Error is: MP-BIOS bug: 8254 timer not connected to IO-APIC Log file is: dmesg2 3) Settings B: + Cool'n'Qulet - enabled (changed) + ACPI APIC support - disabled (changed) * MCP61 ACPI HPET TABLE - enabled Error is: [Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands. Please report this to the Linux ACPI maintainers and complain to your BIOS vendor. Log file is: dmesg3 3) Settings B: + Cool'n'Qulet - enabled (changed) * ACPI APIC support - enabled (default) + MCP61 ACPI HPET TABLE - disabled (changed) No errors!!! Log file is: dmesg4 So, that you can see the reason was in MCP61 ACPI HPET TABLE setting. Have anybody got some ideas about this situation? ** Attachment added: dmsg.zip http://launchpadlibrarian.net/30547759/dmsg.zip -- powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands https://bugs.launchpad.net/bugs/398109 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

It may be worth checking that Cool 'n Quiet is enabled in the BIOS.

Hey swordfish, A thought for a little more info for the Linux team. Since this problem is in the BIOS programming. What brand bios do you have? Phoenix? AMI? etc...
