Explanation

The DMA driver has encountered an error due to a hardware checkstop during a write operation in TCE mode. Look for an error log entry generated by PRD (processor runtime diagnostics). (The checkstop needs to be analyzed to determine the root cause of the failure. The DMA failure is a secondary effect of the hardware checkstop.)

Response

If this is a tracking event, no service actions are required. Otherwise, use the FRU and procedure callouts detailed with the SRC to determine service actions.
