Abstract: Upon occurrence of multiple errors in a central processing unit (CPU) package, data indicating the errors is stored in machine check (MC) banks. A timestamp corresponding to each error is stored, the timestamp indicating a time of occurrence for each error. A machine check exception (MCE) handler is generated to address the errors based on the timestamps. The timestamps can be stored in the MC banks or in a utility box (U-box). The MCE handler can then address the errors based on order of occurrence, for example by determining that the first error in time causes the remaining error. The MCE can isolate hardware/software associated with the first error to recover from a failure. The MCE can report only the first error to the operating system (OS) or other error management software/hardware. The U-Box may also convert the timestamps into real time to support user debugging.
