Abstract
LIC-COMM-INCORROUT Freeze error on 5767/5768 Ethernet

Error Description
Under heavy system I/O load, an Ethernet adapter with type 5767
or 5768 may fail.  A Product Activity Log entry with System    
Reference Code B025A6D9 will be created.                        

Problem Summary
Under heavy system I/O load, an Ethernet adapter with type 5767
or 5768 may fail.  A Product Activity Log entry with System    
Reference Code B025A6D9 will be created.                        

Problem Conclusion
Licensed Internal Code has been changed to disable Direct Memory
Access completion timeouts, preventing a freeze error that could
have occurred when heavy bus traffic delayed I/O operations from
completing.
