please guide how to debug these kind of panics.

That's a very old and obsolete kernel version.  Please try running 4.7
and see if the issue happens there.

If you are stuck with the 3.10 kernel, please ask the company that is
forcing you to do that, as you are already paying them for support.

best of luck!
