Kernel debugging is a specialized software skill that involves the ability to analyze system crashes, faults, and errors at the core level of an operating system. This typically requires expertise in low-level programming languages and tools, as well as an understanding of how operating systems work at a fundamental level. Some common tasks for kernel debuggers may include diagnosing hardware failures, identifying and fixing software bugs, patching and optimizing system code, and ensuring system stability and performance. This skill is particularly important in environments where reliability and high availability are critical, such as in mission-critical systems, embedded devices, and network infrastructure.
