I agree, because I've never used Wifi (except for short tests, but not
configured to auto start).

I've noticed this issue often when I change the charge mode. Switching
from wallplug to PC-USB is the way to obtain 30% cpu usage by event/0

Sometimes a suspend/resume may solve the problem. But I think a small
illume cpu indicator may help to diagnose. I've not yet installed E17
successfully to write such an applet, but I'll try as soon as I have
time to do that.
