I have installed SuSe 9.0 x86_64 on a laptop with AMD64 3200+ cpu. The machine is based on a Mitac motherboard (Radeon 9600 etc.). Installation was fine, but when I did 'cat /proc/cpuinfo' it only registered a speed of 800MHz. Oh dear! Where's the rest of the speed? Running an intensive application quickly confirmed my fears, no increase in speed at all. In Windows XP the speed increased according to the load (as did the the noise from the fan). But I don't want to work in Windows ... I tried 'rccpufreqd start' but the daemon wouldn't start ... 'starting cpufreqd skipped' . grep cpugreqd /var/log/messages revealed 'CPU frequency scaling not supported with current settings! Is this machine supporting speedstep or powernow technology? Please have a look in /etc/sysconfig/powermanagement'. So I tried setting CPUFREQD_MODULE to "powernow-k8". rccpufreqd start resulted in 'failed' ... grep -> "CPU frequency scaling not supported". I checked the kernel configuration which says that frequency scaling is supported as a loadable module. I checked for the module and there it is at /lib/ A quick check using insmod revealed that the powernow-k8.o module woud not load into the kernel. Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.

bummer that it's stuck at low speed. I disabled cpufreqd because it caused my motherboard to hang, but at least it's running at full speed when it boots. [...]

You're doing pretty well actually! contact both the laptop manufacturer and the bios writers and see if there's something they know about the info you have posted. I'd think it be in their interest to have somebody like you advertise how great their computer is vs how crummy it is :-) I think there's a bug in cpufreqd - disabling it has saved me a lot of problems. So another place to check is the linux kernel and who ever is writing that routine. I wouldn't mind getting the whole ACPI system working, but I can at least live without it. Patience, persistence, truth, Dr. mike

I suggest to get a new BIOS, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SuSE Linux AG, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126
