See ../docs/kernel-patches.md for more information on kernel builds.

To build with various debug options enabled, build the kernel with make DEBUG=1. The options enabled are listed in kernel_config.debug. This allocates a significant amount of memory on boot and you may need to adjust the kernel config on some systems. Specifically:
