So, it's working in 9.1 but not in 9? Since any fix to 9.0 would be in 9.1 are we just concerned with understanding what happened, or is there a specific reason we need to know what changed so that a specific fix to 9.0 is needed? I'm sure that there is a bug in isp where it can ask for more than a page's worth of queue space mapping but can't deal with things if you get more than 1 segment descriptor back. I need to fix that, but I won't be able to get to that for a couple of weeks. It's possible that the FC-TAPE changes triggered this because that threw more of a load on the control space. I'll try and calculate a change to MAXISPREQUEST to re-fit within a page some time today. -matt
