From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux) (KHTML, like Gecko) Description of problem: After a fresh install of FC3 i see the following message in my syslog: powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09b) powernow-k8: BIOS error: numpst must be 1 Because of that cool and quiet (cpufreq / powernow) does not work. Searching the web brought up the following : http://www.redhat.com/archives/fedora-test-list/2004-May/msg01499.html It seems that the acpi-fallback option does not work. However i already run the latest available kernel of fedora-core. My Motherboard is an MSI 6702 (aka K8T Neo-FIS2R) with the latest bios (v1.8). Cool and quiet support is enabled in bios. If you need more infos feel free to contact me. Greetings Jan Version-Release number of selected component (if applicable): kernel-2.6.9-1.667 How reproducible: Always Steps to Reproduce: 1. Boot stock fedora core 3 kernel on the above Mobo 2. Try to enable cpuspeed 3. watch the above message Actual Results: My dmesg-output : powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09b) powernow-k8: BIOS error: numpst must be 1 Expected Results: I expespected powernow to work ;-). Actually when i used linux-2.6.9-rc3-mm3 on an debian (testing) system powernow worked for me. Additional info:
Created attachment 106808 [details] dmesg output when debug-acpi is enabled in kernelconfig Hi i recompiled my kernel with CONFIG_ACPI_DEBUG=y and attached the full dmesg output. Unfortunately the powernow-k8 driver stays quiet and does not say why he is not using acpi. Greetings Jan
I tried kernel 2.6.10-rc2-mm1 but it would not boot under fedora. So i fired up Debian (testing/i386) and tried the kernel there. Powernow is working : powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09e) powernow-k8: 0 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV) powernow-k8: 1 : fid 0xa (1800 MHz), vid 0x6 (1400 mV) powernow-k8: 2 : fid 0xc (2000 MHz), vid 0x2 (1500 mV) So could you please update the powernow driver in Fedora Cores kernel, so that me and others could use this feature. Thank Jan
I'd like to confirm the bug; I also have an MSI K8T Neo with latest bios (1.8), and see the same error on bootup. I'm also running FC3 x86_64.
linux Kernel 2.6.10-rc2 runs fine under fedora core 3 und has the problem fixed (at least for me), so you may want to try this kernel out. Greetings Jan
It seems that the issue has reappeared in Fedora core 4 Kernel 2.6.11-1.1369.

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
Fedora Core 4 and kernel-2.6.14-1.1656_FC4 still has this problem. dmesg is showing powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.50.4) powernow-k8: BIOS error: numpst must be 1 The system is running on a Mobile AMD Sempron 3000+. Also, running service cpuspeed restart gives: FATAL: Error inserting powernow_k8 (/lib/modules/2.6.14-1.1656_FC4/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device The file powernow-k8.ko is there, though.
