My only hangup is that this problem is a new one since having fixed the code with the fix from http://lists.freebsd.org/mailman/htdig/freebsd-questions/2005-April/ 084211.html That fix was in April. I had a solid whole month without any of these messages, and then they appear right around when I updated my 5.4- STABLE installation. I suppose the older installs could have suppressed these messages completely while the new one defaults to 5. Does anyone have any idea if this is true? I imagine it is highly possible that it has had the hardware glitches all along and the only thing that has changed is how -STABLE deals with it.
