--- Comment #23 from Mario Limonciello (AMD) (mario.limonciello@amd.com) ---
All of these events are so intermingled, we need to decouple and characterize
log events to understand which are issues we're hitting or not.

From what you've described there is at a minimum a firmware bug causing a
spurious IRQ1.  I suspect this when paired with any other number of wakeup
events is causing either a system wakeup or not getting into the deepest state.

So your "disabling keyboard wakeup" is probably a good idea until HP can fix
that firmware bug.

I also hypothesize my patch will help battery life when there are these types
of spurious events but I don't really know for sure.

So with the same debugging lines I suggested in comment #12 and my patches
suggested we need you to issue a suspend and keep track of what you did when so
we can correlate it to the events shown.

That sounds good to me.  Then we'll know if the EC had spurious events that
woke the system and whether it went back to deepest state and how long.
