"[] I use WARN_ON instead". Instead of what? 

Changelogs must be self-contained. I had to look at the diff to complete that 
sentence in my mind.

Please don't ask reviewers to go back and forth commit messages and code in 
order to get the whole picture.

However, my suggestion is only about the formal aspects of proper patch 
construction. The actual top priority is to properly solve this problem using 
the tips provided by Greg K-H with his review.
Thanks,

Fabio

P.S.: "chrashing" => "crashing".
