What about Atlas? I had repeatable system lock with"queue full"
sympthom, with aha2940uw and Altas-II. I had to disable tagged queueing
complety to survive. That was at the times of 2.0.30. With .31, tagged
queuing seems not to cause the troubles, given the fact I didn't dare to
enable SCB paging. But all of that doesn't look promising for me.
