In this post we explore double faults in detail. We also set up an _Interrupt Stack Table_ to catch double faults on a separate kernel stack. This way, we can completely prevent triple faults, even on kernel stack overflow.
This post explores the double fault exception in detail, which occurs when the CPU fails to invoke an exception handler. By handling this exception we avoid fatal _triple faults_ that cause a system reset. To prevent triple faults in all cases we also set up an _Interrupt Stack Table_ to catch double faults on a separate kernel stack.
