I logged vmstat 2 output [1]. Here are the last 300 lines that show the situation before and after the crash till I rebooted. I can't really read much out of it, but maybe someone else? For some reason this time it took a while for the problem to show up again (several days). I wonder if that has anything to do with me setting up a swap that I didn't use before. My main memory is more than sufficient though. @Tuxce: Killing the gnome-shell process restarts the gnome shell but will result in an immediate freeze again. The only solution is restarting the system.
