Are you asking if it booted successfully after flashing? Yes it did.
But, in the Kernel Version it still says : "BuildUser@BuildHost #1". Wouldn't it be different if you recompiled it?

thats good enough...

the kernel is from stock kernel.sin, as no kernel sources are available at the moment i cannot do a fresh clean compile...

anyways i am updating the 1st post with the info that the kernel is tested on a device and it works

Waiting for Sony to release the sources so that we can lay our hands on our very own DoomKernel

i wont be working on custom kernels for Xperia P, Sola & U as i dont have those devices and in anycase i dont have time to work on them...

honestly i would have LOVED to, but due to lack of time i will be barely able to support the existing devices i have (ARC, PLAY, S)... so i dont want to take up additional responsibilities when i know that i wont have time to work on those devices as of now...
