A computer-implemented method includes storing commands and maintaining an order of receipt of the commands in a command processing unit. The commands include address translation cache miss commands that are organized as one or more linked lists and stored in a content-addressable memory (CAM). All nodes within a single linked list include commands having addresses that map to the same hash value. Based on receiving a memory fetch completion indicator for a cache entry for a command in a head node in a linked list, all of the commands in the linked list are returned. The returning includes sending the commands in the linked list to an address translation unit in an order specified by the linked list.
