A few terminal windows, a few Firefox pages, Thunderbird, and VirtualBox (with the extension pack loaded) running one small Linux VM with 512Mb memory (very lightly loaded as it's only running bind9). I think (but don't have perfect certainty on this) that some of the crashes have happened without VirtualBox running. Also running rsync so that backuppc on a separate machine can back it up over the network (backuppc has been a real lifesaver with all the reinstallations!) After booting the system runs happily for a while then the GUI freezes. This can take a few hours or up to a day or two. You can still ssh into the system, and if you do "top" it typically shows 100% CPU load on systemd-timesync. The same happens whether I use nouveau or the proprietary nvidia driver (361) I have tried a complete reinstallation (4 times already, starting to get quite frustrating) using the proprietary drivers and NOT using the proprietary drivers and the same still happens. The most recent time was with nouveau, and Xorg.log has a number of entries like this: (EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
