Several callbacks are called after that message.  Anything that
registers with the shutdown_post_sync or shutdown_final event handler,
for example, and the dump routine if you are using "reboot -d".

Before trying to diagnose this, however, make sure you are running with
sys/dev/usb/ehci_pci.c 1.30 (which has also been MFC'd to 6/7), as that
seems to have been the cause of most of the recently reported "hangs
after printing uptime" PRs.
