I am not sure this is an opensuse 10.2, or motherboard, or bios bug, but when I cat /proc/cpuinfo, I get two different speeds listed for two identical cpus on in my system (look at the listed cpu MHz entries) :
more /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 33 model name : Dual Core AMD Opteron(tm) Processor 270 stepping : 2 cpu MHz : 1000.000
That is the frequency the cpu currently runs at. We power down the cpu when it's idle. Give it some more to do and it will increase again.
The feature is called cpu frequency scaling, you can control it with the powersave command.
Everything is working fine ;-)
Is it possible that there is a kernel-level 'race' here while it fetches information for each core? I.e. if frequency is changed due to whatever reason between two successive show_cpuinfo()?
