I get kernel panic when loading and unloading presented modules saying
BUG: Unable to handle kernel paging request.

2.
I've written short script that finds all available modules on system and
tries to
load and unload them - see attachment or http://pastebin.com/dphQp2D3
I've tried several machines with different kernels and architectures
and always got kernel panic, oops or not responding system.
The problem is the panic is always caused by different module on
different machines and with different kernels but some of call traces
are similar and they always begin with "BUG: unable to handle kernel
paging request at" + address.
I've been using module-init-tools 3.9 and 3.16 (most recent).
Here are examples of output:
stable kernel 3.0 on x86_64 machine: http://pastebin.com/WKAEdSjE
stable kernel 2.6.39.3 on x86_64 machine: http://pastebin.com/3XNy5n3B
stable lts kernel 2.6.32.43 on x86_64 machine: http://pastebin.com/rYzH6y2B
stable lts kernel 2.6.32.43 on i386 machine: http://pastebin.com/qSnLTch2

The problem does not occur when loading and unloading one module.
The problem does not occur after certain amounts of loaded modules.
When I choose a different order of modules (e.g. using sort) I get panic
on different module.
