Abstract
A mechanism is provided for predicting cache array bit line or driver failures. This mechanism checks for five consecutive errors at different addresses within the same syndrome on invocation of event scan polling to characterize the failure. Once the failure is characterized, it is reported to the system for corrective maintenance including dynamic and/or boot time processor deconfiguration or preventive processor replacement.
