You have to write: # modprobe p4-clockmod It means no ko extension. Same result. The p4-clockmod is not in /lib/modules/2.6.29.3/kernel/arch/x86/kernel/cpu/cpufreq/. But I tried the acpi-cpufreq.ko and got the same result. -- dump of screen # ls

--- No i do not think it is a typo because I get the same exact error that it is missing where as it was available 2 kernels ago? Do you mean modprobe can not find the proper module file when it faces two and more kernels in same machine? I think this would not happen. File Bug Report?

I had similar problem in the past. I used 586 kernel and it didn't work. Do you have 686 kernel? If yes, can you send us the output of the following commands: # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies # cat

If you need a newer kernel to use that patch, I would recommend something that runs more cutting edge for that server, maybe Gentoo or Fedora 9. I don't recommend patching CentOS with a new kernel as you lose the main benefit for using an Enterprise distro .. stability. You meant I should not

It seems that you tried to patch the CentOS kernel and it didn't work. I am doing this experiment. And, I don't know what would happen. Different from previous work, I don't patch the kernel from www.kernel.org but patch the one download from www.centos.org. I would use the same version

PF_RING seems to be used for the newest version of ntop for faster packet capture and analysis. Is that what you are trying to accomplish? Yes. this is the reason why we turn back on PF_RING to patch the kernel. Generally, the libpcap can not meet our need to capture the network packets. Or
