The RAM seems fine. It looks like it is the mainboard or a harddisk. The issues 
have magically disappeared since 3 weeks, but I have not done any suspend2disk 
since then anymore. Before that I had suspended the machine on the evening and 
resumed when I came to work. So it's possible that there was some corrupted 
stuff in the image.

This is the smart output I got of one disk yesterday:

A mandatory SMART command failed: exiting. To continue, add one or more '-T
