Re: Which is it?
Are you sure?
The article says a device "unnecessarily" sending a signal to the CPU to slow down. But what if it is a motherboard design fault causing said device to overheat under certain conditions? Until someone works out a way to run a thermal camera over the board under realistic operating conditions it's hard to be sure.
I used to hate this kind of problem, with something that only goes wrong in the enclosure, till a colleague told me of his even worse experience debugging a certain military avionics system. The rack of boards had air flowing over at over 500fpm. To diagnose a board problem you were supposed to put in an extender board so that the offending board stuck out of the rack. Into still air. Whereupon the ECL promptly got hot, and even if you were able to work while a colleague aimed a hairdryer on cold at it, the temperature change promptly threw the timings off.
