Note that with AMS we're better off -- it has two interrupts telling us when something is wrong. Hence, most of the discussion about loads of input values only applies to hdaps, the actual head-park functionality can be implemented with AMS without ever reading any sensor values. Hence we also need much less complexity in userland -- once an interrupt comes in we trigger the hd park... johannes
