:I have found a reliable way to trigger it:
:switch to single user mode
:mount -a
:cd /usr/src
:make installworld && make upgrade && reboot
:
:print_uptime() has not been called in my case.

Hmm. If the uptime is not displayed this implies that the
vfs_unmountall() call is getting stuck.
Try with the latest master, I made some adjustments that might effect
raw device closes. If swapcache is turned on try turning it off
(though my latest patch turns it off on shutdown automatically, too).
So far I cannot replicate the issue on my test box. I did have
reboot issues in past related to swapcache but those are gone now
w/my recent commits.
Other possible causes: tmpfs, vn, usb mounts, procfs, etc.
If you can reliably replicate the problem you may have to add a bunch
of kprintf()'s to the umountall iterator to track down which filesystem
is getting stuck. I have included a df of my test box below.
