The Force 3 disconnected 35 minutes ago and it was one of those times where it left the system completely frozen. (it's the 2nd time iirc)
(it froze in the middle of a loop)

So, it does not look like the new firmware has made any difference so far.
I'll probably secure erase it one of these days.

Yeah, you better get a bigger apartment

It's hard to tell, if the user pattern is to restart every day one might not get hit by the issue at all, too many factors.
In my case most disconnects are somewhere between 24-35 hours.

I can safely say that the freeze is easily reproducible on several systems.
There are still a few more options to try in my case, like disabling power saving, will give it a try.
