I disagree. If you have a system that generates SMIs in this extreme 
frequency, you're better off stuck than running on such an unstable 
system. The user _will_ see messages on the console if this happens. 
Note that apparently there are few people who have trouble with this. We 
did see problems, but never had more than 1 SMI disturbing the 
calibration procedure.

Anyway, here is another patch that defines max iteration counts. I 
haven't added a "Signed-off:" line, because I prefer the original version.
