I need to compile an old kernel 2.6.23 (downloaded from linuxkernels.com) in order to use it with a real time patch (it's a long story...), I installed ubuntu 10.04 which has a kernel 2.6.32-43-generic-pae. I decided to simple copy ubuntu configuration:

cp cp /boot/config-2.6.32-43-generic-pae /usr/src/linux-2.6.23/.config

I recompile the kernel:

make menuconfig 
make
make install
make modules_install
mkinitramfs -o /boot/initrd.img-2.6.23-MYVER 2.6.23-MYVER

note that in the config I make this edit: I remove the module versioning support under loadable modules section. (this step is required by the patch).

At start, I get the title error:

cpufreq: no nforce2 chipset error

how it possible, since I copied a working configuration? Maybe is because of that only flag I disable?

不确定，但是当我复制现有的 .config 时，我首先运行“make oldconfig”以确保我已全部同步。然后，如果我想以交互方式查看/更改任何设置，我会运行 make menuconfig。
