Abstract: A system and method for shortening the system management mode when a fault occurs in hardware component in a computer system is disclosed. The computer system has hardware components that may have faults. Notification of an error in one of the hardware components is received through RAS silicon on a processing unit. The error is detected from the hardware component by a system management interrupt handler executed by a bootstrap processor core. The error data is logged into a system error log via a system control interrupt handler executed by the processing unit. The system management mode is avoided during the logging of the error data. This prevents other processor cores being suspended from the system management mode.
