A computer system includes a plurality of buses; a device connected with the plurality of buses and configured to generate an error message when a failure has occurred on a first bus of the plurality of buses; and an IO control circuit connected with the device and configured to close the first bus in response to the error message transaction. The device includes a plurality of bus control sections respectively connected with said plurality of buses. The IO control circuit transfer a first operation transaction to the first bus through a first bus control section, and closes the first bus in response to the error message transaction in a bus failure operation when the failure has occurred on the first bus.
