Can you see the system log while you ssh? It could be interesting to see what 
happens just before the freeze, but, unfortunally, chances are you wouldn't 
find anything relevant.

Anyway, it looks as if this is related to a nasty bug that has made its way in 
k/ubuntu soon after the last nvidia update (D830 has a nvidia card, right?) 
when gutsy became release.

So you might get a picture of the situation by reading these:

and see if you think that what you got sounds similar.

In my case I had this bug on my desktop, but not on my laptop. I solved it by 
installing the new nvidia driver

This can be achieved manually or, in a smooth and easy way, via envy:
