Not powertop, but yes tlp. Very interesting. I will uninstall and see if that solves the problem.
Another observation I just made: If I suspend the laptop with USB devices plugged in, they are still detected when I restart. I guess I could work around by leaving some small USB device plugged in (one of those wireless mouse things) but obviously that's a real hack. Still, the observation may be a hint as to what's going on or what I might look at next. I will disable TLP and report back.
