[SOLVED] Kernel compile - missing builtin modules

Hello! I have compiled several kernels following the instructions in the  Kernel/Arch Build System Wiki. Upon installation, initramfs is not able to hook the kernel modules. The modules missing are standard builtin modules and I confirmed in the config file that they were all assigned as "=m". I am not sure how to proceed from here, any help or pointer is appreciated to get these hooks to work.

Thanks for your help!

Re: [SOLVED] Kernel compile - missing builtin modules

I think you are confused about what hooks are, and confused them with modules (they are not the same thing; see mkinitcpio page in the Wiki). There are no such hooks listed on your error lines, unless you have created some custom hooks. Hooks are not done in the Kernel configuration (but in /etc/initcpio/install...).

Most probably you want to list said modules (not hooks!) in MODULES=( ... ) -variable of the mkinitcpio.conf.

Either that or I'm totally lost on what you are trying to do.

Perhaps post mkinictpio.conf here to make sure what is going on (I assume you get the same errors even on the stock kernel packages?).

Re: [SOLVED] Kernel compile - missing builtin modules

Doh! Thanks so much for your response. You were right, I was trying to load the modules via hooks which was obviously wrong! Thanks!
