Debugging Linux Kernel Dumps with the Crash Utility

When a Linux system crashes, finding the root cause requires a systematic approach to reading and analyzing kernel core dumps. This text-based course guides you through the essential concepts and practical steps of kernel debugging, helping you turn cryptic system failures into clear, actionable insights. You will learn to navigate the kernel's state at the moment of a crash with confidence, using industry-standard tools to inspect memory and analyze system behavior. What you will learn: Understand the foundational architecture of Linux kernel panic states and core dump generation; Configure the crash utility and set up the necessary debug symbols; Analyze stack traces and inspect active processes to pinpoint where a failure occurred; Navigate memory structures, search kernel memory, and examine system variables; Disassemble kernel functions to read and interpret assembly instructions during a crash; Apply modern debugging workflows to isolate memory corruption and system hangs. Starting with key terminology and foundational kernel concepts, this course guides you through step-by-step written explanations and practical command-line examples. It is designed for system administrators, kernel developers, and DevOps engineers who want to build a solid foundation in low-level system debugging. No previous kernel debugging experience is required. Start reading today to master the essentials of Linux kernel analysis.
