I spent lots of time configuring my Ubuntu 8.10 installation, installing all the required softwares. The best thing i could do was to install Prozilla- the download manager which is really awesome. Also i installed all the IDEs, RDBMS that i use. But when i tried to shutdown my system it used to hang. This used to annoy me like hell. I then googled for this problem and came across the following solution which worked for me:

Open the file /etc/init.d/alsa-utils with the following command:
sudo gedit /etc/init.d/alsa-utils
The file opens in Gedit and around the line 353 you’ll find the instruction “stop)”. Below this instruction you should add these two instructions:
ifconfig wlan0 down
ifconfig eth0 down
So, the file should be this way:
stop)
ifconfig wlan0 down
ifconfig eth0 down
EXITSTATUS=0
After doing this, save the file, close it and restart or shutdown Ubuntu and verify if the problem continues.
