Well it would appear that you were right about it being a hardware
problem. I had a rather unstable ide harddisk at /dev/hdb
The moment I removed it from the computer things started to work. So now
things work great.

So my problem is solved - should I still file a bug? 

Thanks for all you help, and Martin thanks for turning off my machine
when you were done. It made my bedroom a little more quite :-)
