Abstract
A method, system, and computer program product are disclosed for diagnosing and recovering from I/O subsystem errors. A data processing system includes a computer which includes a power subsystem and at least one I/O subsystem. A determination is made that an error occurred in the I/O subsystem. Registers in integrated circuits included within the I/O subsystem are accessed utilizing the power subsystem in order to diagnose the error while the I/O subsystem is in an error state.
