Well, right now I'm trying to figure out whether there's a race condition in setting up / enabling the TX queue that I haven't yet seen before, or whether we've hit another one of those corner case bugs in the TX queue handling. I may add in a hack to the completion code that checks if the queue isn't active and if it isn't (but there's frames in the TX queue), it restarts TX. adrian
