Can you describe how this could trigger with a pristine kernel ?
This can be reproduced with our custom network traffic to simulate malware.

Point is the user can modify certain packets and can cause a kernel crash
causing blackout to all the linux boxes hosting services :(

Eric is kindly asking you exactly how to reproduce the crash, so he
can 1) fix it and 2) generate a test case that gets run all the time
in the future.

Please answer his question directly instead of steering the conversation
endless towards other aspects.
