Hi.

I have a Presario 710EA with Debian 2.6.4-k7 kernel image installed. With modconf I tried to install the PowerNow-k7 module but I get a message that tells me that the device is in use.
As a matter of fact I have activated and loaded all ACPI modules and another module freq_table that is used by ACPI and that modconf dowsn't let me unload. I'm not able to understand who is conficting with powernow module and why it isn't loading.

WHich are the modules that mustn't be loaded in memory so that I can install powernow for my DUron 900 processor?

Thanks

rmmod acpi

it's the cpufreq-acpi module which doesn't work on most (all?) powernow systems. Then, powernow-k7 should function properly. A patch which will fix this behaviour and let you register powernow-k7 independently of whether the non-working cpufreq-acpi module is loaded is in the queue to Linus already.

Odds are that you've loaded the acpi cpufreq driver. Cpufreq doesn't support >1 driver being loaded.

So what should I be looking for in lsmod?
Must I simply remove it with rmmod and load the power stuff for AMD processors?

Cheers

rmmod acpi
modprobe powernow-k7

should work. You can disable CONFIG_X86_CPUFREQ_ACPI in your .config instead, though...
