A build took ~10min on a 11gen intel cpu with nvme disk

Builds fail mostly while building modules. Then easiset way out: you probably don't need the module, so deactivate it in .config

Kernel is not signed -> safeboot needs to be deactivated. For signing kernel or modules look elsewhere (e.g. kernel tree docs)
