Bizarre... The kernel is normally first opens a new tty and switches to
it before suspend. It seems that this opening of a new tty is
conflicting in some way with X "nv" driver and causing that freeze. Are
you also using an fbdev like rivafb or nvidiafb or are you defaulting to
offb ? If you do, Can you try booting with video=ofonly and tell me if
it helps ?
