B1811004

Explanation
 The DMA driver has encountered an error due to a hardware checkstop during a read operation. 
(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.
