But when I attempt to enable power management, they start rising. Sometimes 60/second, sometimes less. Things are fine as long as I don't enable the off mode; when I enable the off mode, "echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode" interrupt counts start rising immediately. "echo 0 > /sys/kernel/debug/pm_debug/enable_off_mode" stops that. But no matter what configuration, activity LEDs still indicate it is busy, and idle power consumption is cca 53mA. > > "Lock button" interrupt stops increasing as long as I hold the lock > > button in the "unlock" position.
