That alone isn't enough - I frequently halt my laptop with no network cable attached (to re0), and never noticed any particularly long waits. I had exactly the same issue - neither reboot nor shutdown worked (as in shutdowning or rebooting the computer). Then I found this thread and started to look at network interfaces. I had lost carrier to mos0. So I tried to lookup or bring down the interface. ifconfig just hang at mos0 and didn't respond to ^C. And ^T said that it was usbsync state. Then I just plugged mos0 out (as it is an usb network card) and reboot immediately worked. P.S. That's on 4.6, haven't tried -current.

I forgot to say that I was only talking about real hardware machines, not virtual machines. On the machine I saw it last, there are two bge(4) and two em(4) interfaces, and they are all active (HP G380 or so). I also forgot to specify what long means. It means that there can easily be 5-15 minutes before the actual shutdown appears to finally trigger, but since I have my shell back in the meantime, and thus tried to issue the command several times in a row (usually, issuing the shutdown command immediately renders the shell unresponsive), I can't say which invocation actually did the trick. This is especially discomforting when already running on UPS battery and/or working with remote systems... TIA! -- Kind regards, --Toni++

I usually log in as a regular user, then su to root, then do stuff (really old-fashioned). In the most recent example, PostgreSQL was not involved. I even turned off several things, so the only big service running should have been squid. Anyway, squid is configured to shut down after 30 seconds, so there's still a gap of several minutes between first issuing the command and actually shutting down. As I said, this happens irregularly, or at least, I didn't detect a pattern yet. Most of the time, I can shutdown or reboot the affected machines without any problems, but sometimes, they just hang.
