Try Strong Steve's ROM. I was getting LOS with the LoStkernel. Problem is XDA and him got into some thing over them wrongly moving his ROM to theme's, and that just happened today so you may have to search around on where to get it. Here is a link to original, but he deleted the hosting info:
[THEMED ROM][Upd 11/3][Odexed, ICS Theme w/Batt%,1x/3G,Hotspot,NoCIQ/Blue overscroll] - xda-developers
and then here is thread that should post where he moves it to:

I was ready to return the phone due to battery, LOS, and rebooting issues before putting on his ROM/kernel combo and have had no issues since.
