Description of problem: cpufreq was working with earlier rawhide kernels such as kernel-2.6.11-1.1177_FC4 but now does not. This is on my iBook G4 running a mix of FC3 and rawhide. $ cat /proc/cpuinfo processor : 0 cpu : 7447A, altivec supported clock : 1066MHz revision : 1.1 (pvr 8003 0101) bogomips : 530.43 machine : PowerBook6,5 motherboard : PowerBook6,5 MacRISC3 Power Macintosh detected as : 287 (iBook G4) pmac flags : 0000001b L2 cache : 512K unified memory : 768MB pmac-generation : NewWorld Version-Release number of selected component (if applicable): 2.6.11-1.1208_FC4 How reproducible: Always Steps to Reproduce: 1. cpufreq-info Actual results: analyzing CPU 0: no or unknown cpufreq driver is active on this CPU Expected results: Additional info:

thanks, here is all ok now. $ uname -rmp 2.6.11-1.1219_FC4 ppc ppc $ LANG=C cpufreq-info cpufrequtils 0.2: cpufreq-info (C) Dominik Brodowski 2004 Report errors and bugs to linux, please. analyzing CPU 0: driver: powermac CPUs which need to switch frequency at the same time: 0 hardware limits: 667 MHz - 1.33 GHz available cpufreq governors: userspace, performance current policy: frequency should be within 667 MHz and 1.33 GHz. The governor "userspace" may decide which speed to use within this range. current CPU frequency is 667 MHz.
Yup, this works for me now: 2.6.11-1.1225_FC4. Closing RAWHIDE.
