Of course it depends on how many modules, etc, but it’ll probably take 1-1.5 hrs for the kernel and maybe 3-4 hours for the modules, and even make deps will probably take 30 minutes. With more RAM these times would improve considerably.
How is the Linux kernel built?
The Linux kernel has a monolithic architecture, which means that the whole kernel code runs in kernel space and shares the same address space. … Once a kernel module is loaded, it is part of the monolithic kernel and shares the same address space of the code that was included at kernel compile time.

How hard is it to write your own kernel?
It’s really not as hard as you think. If you just take it step-by-step, basic access to things like keyboards and hard drives is pretty simple. I’ve written a basic, read-only poll-based IDE implementation in about 150 lines of C, and a PS2 keyboard implementation in less than 100.
