I'm not a member of any of any Nvidia forum. I'm more of an advanced
Debian user, with a technical background as a tester. All the searches 
that I
just did regarding mutex_unlock() and the driver point back to this 
post.

You really are doing the best anaylysis I had found. Unfortunately it's 
also
the only one I can find.

Thanks for already doing this investigation.

best regards,
Jelle
