l2_hsic prevents my device from Deep Sleep. How to fix it?

Hello, I have installed BetterBatteryStats and CPU SPY, because I noticed that I had a faster than normal battery consumption when the tab was left alone.
I made a 30 mins test Wifi OFF, Flight Mode On, where the 29 mins of them showed me l2_hsic under Kernel Wakelock -> Since Unplugged.
Does anyone know what causes this and how to prevent it ?
Thank you.
( I am running Stock ICS 4.0.4 rooted)

How is the batter setting on the app? Most of the apps I use are set to Miui battery. The only app that I set to not close is FB and messenger with no restrict on battery. NO battery drain issue so far. I'm on 8.8.23 developer rom.

Crazy battery drain: 1% per min

Hi,
I have H830, 7.0 stock ROM rooted. I've disabled the update so has been running the same ROM for a while now.
Recently, it started to have severe battery drain, at the crazy rate of 1% a min.
Here is what I can see in Better Battery Stats (BBS)
Process view does not show a rogue app
Partial Wake Lock shows NlpWakeLock and NlpCollectorWakeLock, but not to an extent of crazy. I've read Stopping NlpWakeLock, NlpWakeLockCollector and RILJ but there is no clear answer there
Partial Wake Lock shows a lot of WifiOffDelayIfNotUsed but again not crazy
Alarm android Wakeups at 12 / min. Is this normal?
I've read A Comprehensive (but not by any means definitive) Guide to Wakelocks but did not find anything in the FAQ other than the above
How do I fix it? I have root but can't find anything to try at this point.
Thanks
