This is really not a problem as it happens right at the end of the shutdown after disks are synced and seems to start as the standard background processes are terminated. It usually is reported after vnlru and bufdaemon terminate, but before syncer terminates. (It's very hard to tell much as the screen blanks immediately.) It may be starting as bufdaemon is terminated. This is not causing me any problems, but I wanted to mention it as it certainly does not seem right. -- R.
