I think something in this CSSU update disabled my power kernel? I can't say for certain but the reason I think this is because all apps depending on the power kernel, behave as if its not there, even though I've reinstalled it. So I reflashed my phone just now, first thing I installed was the power kernel, mobilehotspot and QCPU frequency app, all 3 are working fine, I am overclocked again to 1150.
