hi Darin!,
First of all, thanks for sharing
I tried in ubuntu 21.10 your guide, steps 1 to 6 perfect, no problem at all, in 
the 7), when run: sudo make module_install, i have:
No rule to make target 'modules_install'. Stop.

Later when i reboot the laptop (a lot of times), i have a missing
modules error and the boot stay crashed on a initframs prompt.

im missing to do something?.

Regards!
