What are Machine Check Exceptions (or MCE)?

A machine check exception is an error dedected by your system's processor. There are 2 major types of MCE errors, a notice or warning error, and a fatal execption. The warning will be logged by a "Machine Check Event logged" notice in your system logs, and can be later viewed via some Linux utilities. A fatal MCE will cause the machine to stop responding and the details of the MCE will be printed out to the system's console.A
