Abstract
A computer system comprises a computer being coupled to a device via a device interface. The device interface has an error status register and a link status register. An error isolation unit periodically obtains values of the error status register and the link status register. The error isolation unit determine whether an error occurs in the device; determine whether the error is an error to be isolated; determine whether the error is an error to be isolated based on values of the error status register and the link status register re-obtained after elapse of a predetermined time in a case of determining the error is not to be isolated. The error isolation unit detects the error as an error of a protocol caused by stop of a power supply in a case of determining the error is to be isolated.
