The Verge: A major new Intel processor flaw could defeat encryption and DRM protections. https://www.theverge.com/2020/3/6/21167782/intel-processor-flaw-root-of-trus...
I am reminded of about 1992, when the 486 Intel microprocessor was discovered to have a rather serious flaw in its arithmetic unit, with potential errors in the 4th and even the 3rd digit. Intel ended up replacing those CPU's. I wonder if they will do the same thing this time.This particular article https://www.nytimes.com/1994/11/24/business/company-news-flaw-undermines-acc... mentions the Pentium and 1994, but I believe that the 486 had a similar problem. But I am unable to find reference to it.

https://en.wikipedia.org/wiki/Pentium_FDIV_bug Intel has had 1 or 2 other cpu replacement programs, that were much more quiet limited to select/affected customers. Rumor has it you could bitch about TSX-NI and get one too.

It was a floating point error in the math if I remember correctly. Something about the way it rounded off large numbers Rr Sent from my Androgyne dee-vice Fuck you if you don't care for my 'brevity'.
