I'm trying to narrow the source of the infamous 1.4 Ghz scale CPU issue. For those who are not experience this, I will explain: on Tangerine ≥10 kernel versions, the CPU won't scale over 1458 Mhz. It works just fine on stock kernel or Tangerine pre-version 10.
I've erased and format everything, even removed the SD-card, fresh install of CM 12.1 and a few custom ROM that were reported as working nice with T-Kernel ≥10... not a change, it won't go over 1.4 Ghz. I'm trying to figure out what's causing this wild behavior, it might be the device subversion. So, please post your Xperia SP version and what's your case - it's your Tangerine (versions ≥10) allows for CPU frequencies over 1458 Mhz? Thank you!

C5303 14W07 TYPE: PM-0350-BV NOT WORKING

@varioventus this is an old thread but I want to write this anyway. The issue appears only when using the "clean L2 frequency table".
The difference between the label on your SP and mine (on which the issue doesn't exist) is that on the right side I see:
Model: C5303
14W18
SI: 1272-2536
There's something different in the hardware. It's the only explanation!
