CPU-generated (80286+) - DOUBLE EXCEPTION DETECTED

Desc: Called when multiple exceptions occur on one instruction, or an exception occurs in an exception handler

Notes: Called in protected mode if an interrupt above the defined limit of the interrupt vector table occurs. Return address points at beginning of instruction with errors or the beginning of the instruction which was about to execute when the external interrupt caused the exception. If an exception occurs in the double fault handler, the CPU goes into SHUTDOWN mode (which circuitry in the PC/AT converts to a reset); this "triple fault" is a faster way of returning to real mode on many 80286 machines than the standard keyboard controller reset
