A method handles concurrent address translation cache misses and hits under those misses while maintaining command order based upon virtual channel. Commands are stored in a command processing unit that maintains ordering of the commands. A command buffer index is assigned to each address being sent from the command processing unit to an address translation unit. When an address translation cache miss occurs, a memory fetch request is sent. The CBI is passed back to the command processing unit with a signal to indicate that the fetch request has completed. The command processing unit uses the CBI to locate the command and address to be reissued to the address translation unit.
