Hi,

This was an out-of-the kernel module, built under the build environment 
for ARM. Can you point me to the linker script responsible for this?

I specified: --warn-section-align

And it output some warnings. Any clues how I can nail this down?

If someone is interested I can give you the source code and build 
instructions.
