--- Comment #31 from Daniel Gibson (metalcaedes@gmail.com) ---
> Woah! Well play with it and compare EC and PS2 traffic in both cases.

How do I get the EC traffic, besides logging the functions in amd_pmc?

My understanding is that these functions are pretty much the last thing
happening before suspend / after resume, so probably not much should be
happening?

The PS2/i8042/atkbd traffic isn't much different, except of course after resume
it starts a bit later now, and the functions called after resume (resetting the
controller etc) succeed without any additional hacks in atkbd or PS/2 code.
