I have a Dragon Lite Soyo motherboard, and I'm running Knoppix DVD 4.0.2
During shutdown, Knoppix always hangs when trying to unmount the filesystems:


When this first happened, I thought it might be because I was supposed to unmount my hard drive partitions by hand. So this time I unmounted it through KDE before shutting down, but it hung anyway. Knoppix works fine in all other respects.
