kernel panic on WB2448 Intel Bay Trail CPU

We are working on WB2448 switch which uses Intel Baytrail CPU complex. We are seeing boot crash when we are using xenial kernel. Below is the crash log. As a result of this we are not able to mount the disk and proceed with Linux bootup.

This issue is not seen on trusty kernel (3.16.x).

It is also seen in the 4.8.x kernel for Yakkety.

Kernel images were downloaded from packages.ubuntu.com and are unmodified.

Below is the panic:
