Comment(by dsaxena):

 Replying to [comment:4 tvoverbeek]:
 > I have attached the output of dmesg on a joyride-2280 run.
 > The first part is on battery only, with battery almost empty.
 > The last part has mains power plugged in.
 > Note the extended EC traffic every 100 sec. At the end (while plugged
 in) the message sequence is much shorter.

 So the issue we have here is that if we are in the middle of recalibrating
 and the user touches the mouse, we need to start allover again. Were you
 moving the mouse around a lot when you saw the nested re calibrations? If
 not, that means you were seeing completely spurious packets from he mouse.
 :(

 We've heard nothing but goodness about the new driver so far, so this is a
 bit worrysome.
