Debugging - When Nothing Works

Debugging in a low-level environment is a special discipline.

Reality

• No Error Messages
• no windows
• no default logs

What is considered an "error"

• freezing
• reboot
• black screen
• no response

The role of the kernel

The kernel should:

• be able to detect critical errors
• stop the system gracefully
• provide minimal indication of the system's state

Why you need to know this in advance

Without understanding debugging, a person:

• doesn't understand what went wrong
• can't distinguish a logic error from an architectural error
• gets stuck for months
