I can confirm that behavior. On my acer TravelMate 370 I can see that in messages:

Soundsystem or disk seems not to be effected by this issue. The freeze takes some seconds up to some minutes. It can be 'unfreezed' immediatly by pushing the laptop lid button.
Sopping init's acpi services does not help, as it does removing asus_acpi.
