Yes I have also seen a similar degradation between the two kernels. What is notable in your case and mine is that the kernel interrupts are labelled differently between the two cases. There are actually fewer load balancing ticks in the later kernel but other categories eg [extra timer interrupt] are chewing up power. So something appears to have changed but not in a good way and focussing solely on [kernel scheduler] Load balancing tick is not appropriate.
