Reliability has been one of the major concerns of modern computer systems, which may be frequently disturbed by software and hardware errors, unsafe software/hardware interactions, as well as operation errors. While restarting the frozen or crashed system is the usual way to recover from failures, it is demanding to diagnose the root cause of the failure for future software and hardware fixes. Crash dump, or core dump, is a typical way to save the crashed or hang context to persistent storage for future offline debugging and analysis before restarting the system.
