Hi,

I was running different Nvidia graphic cards with different proprietary
Nvidia drivers (see my previous post).

Changed the Nvidia graphic card to an old HD 5670 Radeon AMD and loaded
the catalyst drivers. *Until now no more system hangups has appeared.*
Will try e newer AMD R9 290 card later on.

This explains why my kids PC did not hang at all, due to running it on the
internal Intel CPU graphic.

So for my system, it seems that the freezes was related to graphic card. I
don't know if the bug is in the proprietary Nvidia drivers or in Ubuntu.
Sad to change from the Nvidia, because it always worked like a dream in
Linux.
