Heelp! I broke my modules!!!

[zundra]

Everytime I try to recompile my kernel I seem to break a bunch of modules. When I boot the new kernel I get a lot of error messages saying stuff like: Module couldln't be loaded, or Module not found. Here is how I compile

make mrproper
make menuconfig
make dep
make clean
make bzImage
make modules
make modules_install

Everything I read is telling me I'm doing everything right but obviously I'm missing something. Can someone help me out?

Did you setup lilo.conf or menu.list (for Grub) correctly? Copy the new System.map to /boot as System.map-<kernel version> so not to overwrite the default System.map.

Do the new modules actuall exist in /lib/modules/<kernel version>?

Did any of the steps fails especially the make modules?
