mce_display_on prevents suspend
I try to find what prevents my device from suspending. When I look in /sys/power/wake_lock it contains:
mce_display_on
Which application creates this wake lock and how can I prevent this?

@Thaodan: That wakelock is basically indication that the device is in a state where it should not suspend - like: booting up, shutting down, handling call state changes, display state, touch input state, handling sw updates, compositor service not running, having settings that deny device from suspending, ...
It is also released via timeout rather than explicit unlock action and some kernels do not handle this correctly i.e. in some devices it always shows up when polling via /sys/power/wake_lock whether it is actually active or not. Though IIRC that is not the case with xperia x.
