Hi all, I am using an ASUS K8V Deluxe with 1005 BIOS, Cool 'n' Quiet enabled and running SuSE 9.0. It works well with kernel 2.4.21-149-default. However, using the same sysconfig files and the 2.6.3 kernel the above error is seen when running dmesg. A part from my .config file: # # CPU Frequency scaling # CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_PROC_INTF=y # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y CONFIG_CPU_FREQ_24_API=y CONFIG_CPU_FREQ_TABLE=y # # CPUFreq processor drivers # CONFIG_X86_POWERNOW_K8=m If I do 'modprobe powernow-k8' , the extra dmesg output is: powernow-k8: Found AMD64 processor supporting PowerNow (version 1.00.08a) powernow-k8: voltage stable in 100 usec, ramp voltage offset: 2, isochronous relief time: 3, maximum voltage step: 0 powernow-k8: pll lock time: 0x2, maxfid 0xc (2000 MHz), maxvid 0x0 powernow-k8: fid 0 invalid : 0x0 I've played with the config settings and looking into the 2.4.21 .config files but this is the best I can get. Does anybody know what is wrong here ? Henk.
