the crash captured (kernel 3.10.5)
We are seeing a crash in the LED subsystem. It is caused by some coincident AC
adapter unplug with suspend/resume path perhaps.
power_supply_update_bat_leds calls led_trigger_event with
charging_blink_full_solid_trig. The led_cdevs list of that trigger is iterated,
but it is perhaps corrupted as led_set_brightness crashes with dereference of
-0xd8.
A possible cure can be:
