For many years, developers could not figure out the mystery of OS kernels. The main source of this mystery is the interaction between operating systems and hardware while system's boot up and kernel initialization. In addition, many operating system kernels differ in their behavior toward many situations. For instance, kernels act differently in racing conditions, kernel initialization and process scheduling. For such operations, kernel debuggers were designed to help in tracing kernel behavior and solving many kernel bugs. The importance of kernel debuggers is not limited to kernel code tracing but also, they can be used in verification and performance comparisons.
