I run Debian stable, but occasionally my entire system freezes up -- the mouse doesn't respond to anything I do, etc. and it usually requires a restart.
Another minor issue is that Nautilus' search functionality seems to be totally broken.
These things aren't a big deal at all, but that makes me wonder what is meant by "stable" in the very first place -- I somehow doubt its supposed to mean stability for "home desktop users", as there are simply too many home desktop computers with different hardware/software configurations to ensure stability.
So, what does Debian mean by "stable"?
