I/OAT device will refuse to resume from the Halted state until we clear both CHANERR and CHANERR_INT registers. We only cleared CHANERR so far. So after the I/OAT device encountered an error, SPDK would not be able to initialize it ever again unless it's rebound to the ioatdma driver. Unlike CHANERR, CHANERR_INT is only accessible through PCI config space. CHANERR_INT is only available on I/OAT devices with version < 3.3.
