Upgraded from 7.04 to 7.1 Gutsy..
That went flawlessly and everything seems to work fine.
But am having problems with any other upgrade done daily as i get some GPG key error.
Also my suspend is completely screwed. Never goes into suspend even with the right settings - and if i do a manual suspend, then it freezes and i need to reboot.
But all in all - a very good experience..
