This might give some clue if someone else is experiencing a similar behavior. 

I have also tried to exclusively stop the remounting of the devices over a certain period of time, since I suspect this is the case when the crashes happen.

udisks --inhibit-all-polling

Or 

udisks2 --inhibit-all-polling


Both resulting in command not found.

Interestingly enough it seems related to the udiskd daemon. At least this is what I am seeing for a second in the log upon crash before being presented with login screen.

Another thing I've noticed is that about the same time the crashes started a glitch in E19 appeared as well. Again random, when I am trying to close a window on the taskbar the mouse would move precisely to the center of the screen and does that constantly until reboot.

I believe it's since I installed latest updates two days ago. 

At the time it occurs I get a black screen with a few lines of errors and then back to login screen.

I couldn't memorize what the errors were at the time. I have checked all logs in /var/log to no avail... 

Where could they be, so that I can post more info on the errors ?
