Here's another observation. On my system, the proprietary fglrx driver causes system hangs when enhanced features are used (e.g. Google Earth). This can be resolved by turning the tickless kernel off with the boot option "nohz=off". Only this, no "acpi=force"! as mentioned in some forums. The side-effect is, that now my system shuts down in a stable way since 3 days.
