Any update to this bug? I narrowed this down to sbs and the same "kernel fix" several years ago and have been running without sbs since. It's still present on 4.11. Sucks not having battery and charging info available. Btw this is on a MacBook 2,1. I also didn't see this on systems without systemd if something in that code or module loading/parallel has anything to do with it.
