hello everyone:
I am using Centos5.5 with kernel version "2.6.18",now i meet a problem:
i download the kernel 2.6.18 source code from internet.and i compile it with version "2.6.18Young",As you known,I do the following:
make bzImage
make modules
make modules_install
rename bzImage in /boot
generate initrd file
update menu.lst
when I reboot machine and choose the new kernel,it prompt:insmod:error inserting '/lib/ext3.ko'; -1 Unknown symbol in module
how can I solve it ?
I am using vmware workstation 6.0.
thanks a lot.

Greetingz!

Well, for starters you might want to grab the SRPMS for the kernel you are using, rather than grabbing the "vanilla" source from kernel.org.
Your "real" kernel version can be found with a 'uname -r', and probably looks like "2.6.18-238.5.1.el5" and not just 2.6.18.
This is because of bugfixes and security patches that are applied to the code.

A complete How-To on rebuilding a CentOS Kernel can be found here.
