Buggy Samsung firmware. Just search for "l2_hsic wakelock". –  ce4 Jun 17 '13 at 8:34
    
@ce4 thank you. What can we do about it? –  rabbid Jun 17 '13 at 8:41
    
Not quite sure, what could help. XDA's thread (for the Galaxy S2) is full of posts and there's only little real information. Maybe follow some suggestions mentioned here (and in the linked thread): xda-developers.com/android/… –  ce4 Jun 17 '13 at 8:46
    
Here's another article about an app that tries to detect the culprit: xda-developers.com/android/… –  ce4 Jun 17 '13 at 8:48
    
AFAIK the l2_hsic wakelock is connected to "Fast Dormancy". Might be your modem has some trouble with it, as described in some XDA threads (e.g. here). Also see: kernel - l2_hsic prevents my device from Deep Sleep. How to fix it. Both links are about a Galaxy Note, but the underlying issue might be similar. –  Izzy Jun 17 '13 at 11:37
