Oops. This isn't as simple as I thought. The shutdown problem came back even with Sander's umountcifs script installed. I discovered that if I use a hard wire network connection shutdown is fine and umountcifs is unnecessary. The delayed shutdown occurs with a wireless network. I speculate that the wireless connection closes too soon and keeps the cifs virtual file system from shutting down cleanly. Can anyone confirm or correct this?
