Talking about reliable test cases, I forgot to say that I definitely found 
an interesting one. It doesn't lead to OOPS but perhaps something even more 
interesting. While running countless stress tests I tried running some 
games to stress the system in different ways. I chosed openmw (an open 
source engine for Morrowind) and I played it for a while on my second 
external monitor (while I watched at some monitoring tools on my first 
monitor). I noticed that after playing a while I *always* lose internet 
connection (I use an USB3 Gigabit Ethernet adapter). This isn't the only 
thing which happens: even if the game keeps running flawlessly and the 
system *seems* to work fine (I can drag windows, open the terminal...) lots 
of commands simply stall (for example mounting a partition, unmounting it, 
rebooting...). I can reliably reproduce it, it ALWAYS happens.
