System and Method to Correlate Corrected Machine Check Error Storm Events to Specific Machine Check Banks

摘要

An information handling system includes a central processing unit, which in turn includes a system memory and a first processor core. The system memory stores Common Platform Error Record (CPER) entries in a queue. The first processor core stores the hardware error in a bank of a machine check bank register of the first processor core, and generates a system management interrupt (SMI) in response to storing the hardware error in the bank. The central processing unit receives the generated SMI, clears CPER entries within the queue of the system memory that are outside a specific timespan before a corrected machine check error indication associated with the generated SMI is received, adds a CPER entry associated with the corrected machine check error indication to the queue of the system memory, and disables SMI generation from the machine check bank number in response to the number of CPER entries exceeding the threshold count.
