I have received some report regarding > hangs after this, and IIRC the only operation is to IPI BSP to do reboot? 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.
