freebsd stable - Apr 2008 - What does system do after "Uptime: "?

Hi,

Just wonder what the system would do after Uptime: during reboot?  Will
there be any callbacks be called?  I have received some report regarding
hangs after this, and IIRC the only operation is to IPI BSP to do reboot?

Cheers,

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.
