The slow shutdown is caused by some remote smbfs shares mounted via openvpn: the remote drives are unmounted after the openvpn daemon termination, this induces some long timeout. The solution is to unmount the smbfs shares in a shutdown script before the openvpn daemon termination. I have discovered this issue with this ‘dirty’ patch that displays the unmounted fs at shutdown: http://pastebin.com/Xfiz9nsv With this patch shutting down my laptop appear as: https://drive.google.com/file/d/0BzoWQoMqq1sfcHZyRnlEeTRobFU/view?usp=sharing . For testing the the patch apply it in /sys/kern, rebuild and install the kernel. Set the new OID: # sysctl kern.shutdown.show_umountfs=1 Halt the system: # shutdown -h now Regards, Mauriziohelp
