I have seen freezes sometimes, and they seem to be related to the 
nouveau driver :-(

Lucky you. In my new laptop (Lenovo w540) suspend does not work (there 
is a problem with the nouveau driver)...

See if you have any information in /var/log/messages when you reboot the 
machine. If there is a BUG or Oops report there we could send it to the 
rt list and see if there is a solution.

I just released a kernel I have been using for a while 
(3.14.13-200.rt9.2), it may solve your particular problem or introduce 
new ones... Let us know how it works out.
