Abstract
A device causing a faulty condition in a computer system having devices is isolated by detecting for a faulty condition associated with the devices and identifying the device causing the faulty condition. The devices are coupled to a bus. The faulty condition includes a bus hang condition. The devices are turned off when a bus hang condition is detected. The devices are then turned back on to test the devices. Each device is tested by writing and reading its configuration space. Information on the bus associated with the faulty condition is stored. The stored information is retrieved after the faulty condition has occurred, with the stored information including address, data, and bus control information.
