Description of problem: Version-Release number of selected component (if applicable): cpuspeed-1.2.1-2.fc7 How reproducible: Every boot. Steps to Reproduce: 1. Enable ACPI & CPU frequency scaling in BIOS. 2. Boot into FC7, apply all available FC7 updates. 3. No cpuspeed, CPU Frequency monitor, /proc or /sys files indicate functional speed scaling support. 'Sensors applet' never shows Vcore change. Actual results: It's not at all inconceivable that there's a bug in the BIOS, but if so it's not obvious to me what specific steps / diagnostics I could further take to analyze the ultimate reason for this lack of functionality so that a more detailed bug report to Fedora / cpuspeed / cpufreq-utils / BIOS could be made. I'd be glad to run any reasonable tests that may be suggested to help track down the root of this problem. It'd be nice if there was more verbose diagnostic information somewhere either in /var/log/messages, the output of cpuspeed, cpufreq-selector, dmesg, or some /sys or /proc file to inicate what specifically is absent such that a CPU class that's capable of speed management isn't presenting the capability.

Try booting with some modified grub.conf kernel params. Substitute 'cpufreq.debug=7' for 'quiet' on the kernel line. Grab dmesg output after booting up and attach it to the bug. Should give some good info on why we're not getting any freq scaling. Note that freq scaling works perfectly on my own core 2 quad system, so I'd have to be inclined to say its a BIOS problem at first glance.
Thanks for the kernel parameter information for debugging. I've just rebooted using the 'cpufreq.debug=7' parameter instead of 'quiet' and I see that there is new potentially relevant information in the new dmesg output. It looks like there may be some issues in the BIOS though I'm not sure how relevant those are or if they're such that the F7 PM code is intended to be able to work-around them or not. I can submit the information wrt. the memory address reservation and checksum related problems to the Motherboard/BIOS vendor and hope that they'll have enough information to resolve those before too long. Beyond that I'm just wondering if besides experimenting with other BIOS settings that "shouldn't" make PM work better (but might if there's a BIOS bug), if there's anything I could do in Fedora to get it working and to determine if F7's working "as intended" in the situation. Here I'll list a few of the items I've noticed that concern me as being potentially related problems (though I'm only speculating at the possible relevance), and thereafter I'll send the whole recent dmesg output. Concerning (relevant?) items: ... PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved PCI: Not using MMCONFIG.

Full dmesg: see subsequently attached file and/or forthcoming comment if the attachment process gives me trouble.
Created attachment 161259 [details] dmesg with +cpufreq=7 -quiet options present.
This bit is the most relevant out of dmesg: cpufreq-core: trying to register driver acpi-cpufreq cpufreq-core: adding CPU 0 acpi-cpufreq: acpi_cpufreq_cpu_init acpi-cpufreq: No P-States This indicates that the BIOS ACPI tables aren't providing us with any P-State data, which is fatal to the acpi-cpufreq driver. Pretty sure this is a BIOS bug, and not one we can work around in any sane manner.
Thank you very much for your help in assessing this and for the information on how to get the full debug data. You were correct, it was the BIOS doing something contradictory to the apparent status of the ACPI / C1E settings when other settings were made. I experimented with various configurations and found that I was able to get a functional cpuspeed configuration supporting: P0 = Full speed CPUx9 P1 = Minimum speed CPUx6 acpi-cpufreq: CPU0 - ACPI performance management activated. 1.15V @ acpi-cpufreq: *P0: 2394 MHz, 88000 mW, 10 uS 1.06V @ acpi-cpufreq: P1: 1596 MHz, 59048 mW, 10 uS Those seem to switch appropriately and the Vcores change commensurately. Thanks agaom for all the good work on the cpuspeed / power management code! I'll change this to "NOTABUG".
