modprobe: Module ext4 not found. no dependencies for kernel module 'ext4' found

I rebooted a compiled kernel 3.1.0, and those are the warnings that I am getting:

Did you enable the config option for ext4 in the .config file before compiling.

Don't think I've ever read any article on kernel building that mentions using Kconfig. Most of them follow the steps in this one, if you ignore the Slackware references.

Perhaps he was talking about the make menuconfig edit!

(edit: never mind, an $INSTALLKERNEL script is complaining and it's not Debian.)

In .config resulting from the make menuconfig command, I found "ext4" under file systems option, and placed a *(star) [] besides it. This time I rebooted and was able to login.

Thanks to David from unix.stackexchange.

But the warning of "ata_generic" still persists at boot time! How to solve that?
