Well, just got the first crash/reboot, when I have "Battery fully charged sound" enabled in crDroid Settings -> Sound -> Charging Sounds.
It crashed when battery charge has reached 80% (I have enabled "Smart Charging" to stop charging at 80%).
After disabling "Battery fully charged sound", it works fine now.
This is the Exception:
10-31 13:46:57.100 E/AndroidRuntime(1501): at com.android.server.BatteryService$PlayChargedSound.run(BatteryService.java:1345)
