Wrong kernel? Too much OC, not all devices are compatible with 1128 mhz. Change kernel with half OC , or take the one from Championswimmer Xperia S, works fine for me till now
i use DooMKernel_V6 (recommended on OP), thanks for advice but now still loving the V.14 first release for me with ULBL, battery work great, all app work fine to.
