yeah - and false positives also tend to create apathy and resistence 
against kernel warnings - thus drawing tester resources away from more 
important bugs.

ok. In this case i'd suggest we should just remove the warning. People do 
get scared by needless kernel stack dumps - no matter whether it's marked 
informational or not.
