I am guessing that even your test would trigger the warning,
if you make sure to include CONFIG_DEBUG_ATOMIC_SLEEP=y in your kernel build.

Eric,

Thanks for the pointer, have you ever over looked at something when coding?

I _think_ I was trying to help, not shaming you in any way.

How did the previous email help? I did not get any reply when I asked 
what could be the cause.

My question about spinlock/mutex was not sarcastic, you authored
6 official linux patches, there is no evidence for linux kernel expertise.

That is no measure of someones understanding. There are other OS's as 
well. I have worked on Solaris and other *unix* OS's for over 20+ years. 
This was an oversight on my part and I apologize, but instead of 
questioning my expertise it would have been helpful to say what might 
have caused it.
