I can see all the Intel engineers working hard at providing answers...
If you are serious about this apparent problem, you should contact Intel Support directly, rather than post in the User Community forum:
The i5-2500 processor has recently been pronounced an End of Life product:
Therefore, it is doubtful any changes to it will occur.
You may want to consider the i5-3570 processor, its current replacement, or its next iteration, which is scheduled for Q2 2013.
I pretty much concluded that yesterday... Originally, I kind of followed the proposed "path" for technical support. But when it became apparent that the Intel guys themselves weren't reading this, I finally went ahead and did what you just said. In the mean time, I'll look at what else is out there, including your link... I got to make sure the same problem doesn't exist on those as well, seeing how this problem creaped up on so many of their CPU's listed in my link.
Thanks for taking the time.
well... it appears I'm running into the same issues with the i5-3570!! All the details of the original problem can be found under my hp post here:
