There were a few different kernel warnings, so this date is possibly a
red herring. One is the kernel warning from pin2port(), and this has
nothing to do with Skylake. It's being addressed now.
The problem I can't follow is the PM refcount unbalance found on
Skylake. It'd be helpful if you can give the exact *minimal*
reproducer. The warning shows the result, and it means that something
wrong did happen before that. So, we need the procedure until that
point, not the point of the outcome.
thanks,
Takashi
