Search this post for 'latency', it appears that the filemap_sync issue (which caused apt-get to trigger an xrun) is addressed, as well as several others. One of the more interesting items added is 'low latency RCU'. So, althouh Ingo has been quieter lately, problems are being fixed. Here is the announcement: http://lkml.org/lkml/2004/8/8/125 There is no voluntary preemption patch available yet for -mm2, as this annonucement is just a few hours old. It seems likely that future 'voluntary preemption' patches for the -mm series would consist of little more than the irq-threading feature. This would fit the new development model very well. Lee
