>Description:
Hi guys. I have found something really annoying in FBSD. It's important only for those who use FBSD as a Desktop since servers are halted, restarted very rarely. Here is the problem. 
If you have mounted samba shares which stop to respond and try to restart or halt the FreeBSD, you have to wait for ages before the system halts or restarts, this is due to shares who doesn't exist anymore can't properly unmount for a long period of time ... This ofcourse is not normal for a modern OS so it have to change.
>How-To-Repeat:
mount a remote samba shares, stop the samba server try to halt or reboot the FreeBSD system. You will end up waiting for 5 or more minutes before the system reboots/halts.
>Fix:
Something should be modified to force unmount on attached devices which doesn't respond anymore.
