commit cfcf2d38858078e74ff6d0e34323f1da71a0fe1f Author: Patrick Georgi patrick.georgi@secunet.com Date: Tue Nov 22 10:52:43 2011 +0100
i82801gx: Support power-on-after-power-fail better
Changing CMOS value for power-on-after-power-fail was only honored after reboot, which is counter intuitive (set from "enable" to "disable", power-off, replug device -> device turns on; and similar cases).
