Comment 27 for bug 1019347

I think I have found the origin of my problem. First I tried to disconnect the network before shutting down and I noticed that the system turned off properly (even the monitor).

So I tried to put modprobe -r wl in /etc/init.d/unmountroot and it is working too, then I removed directly the package bcmwl and keeping the connection on the system can shutdown well although the message / is busy is still there.

In conclusion the bcmwl-kernel-source is preventing the system to turn off. Can someone verify if it?
