Well, there is a committed patch in freebsd for their old usb stack
concerning this shutdown freeze. However, I will have to note that I
tried this patch on one of my laptop w/ the shutdown problem; it
didn't work. But you could always try your luck :)

Bug #2167: shutdown/reboot fails after uptime msg
http://bugs.dragonflybsd.org/issues/2167

Author: John Marino
Status: New
Priority: Normal

Target version:

I've mentioned this on IRC a few times, so I thought I'd make it official with
a bug report.

My DragonFly x86_64 machine (AMD Phenom II X4 955) has four partitions, and I
can boot into FreeBSD, NetBSD, and OpenBSD as well.  Those three BSDs have no
problems with "reboot" and "shutdown" commands.  They work as expected.

Typing shutdown -p or reboot will cause DragonFly to freeze after the uptime
message.  Sephe had me tweak something and I believe concluded there was some
interference by the ehci module causing the lock up.

In any case, not having the ability to remotely reboot the server is a medium-
sized problem and it would be nice if DragonFly could support this machine as
the other BSDs do.

Tomorrow Will Never Die

I have this same problem on my desktop (reported in issue #2232).

I also tried the freebsd patch 1.36.2.4 but it didn't work - http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/usb/Attic/ehci.c?only_with_tag=RELENG_6

Now I just disable ehci by adding hint.ehci.0.disabled="1" to /boot/loader.conf
