I did post the prob in the Austin Schuh thread in the RT mailing list. I believe they know what Austins problem is, but Thomas G. is a bit busy it seems at the moment. And I did start reading that thread also. In any case kernel 3.2-rt works great with good latencies, so we will stick to that for the time being. It was just 'feature inflation' that made me move to a later kernel. Not always a good idea. Thanks for your prompt answers. j. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
