Firefox was the only program that was crashing on my "Vmin Shift Instability" bugged CPU. Before I even knew what the culprit was, I filed a bug report with Firefox and the first question they asked me was if my CPU was a Raptor Lake (it was).

- ranger_danger 2mo agoIt does make sense that a browser, being the thing most people would be running all day, basically fuzzes CPUs for free... they generate their own CPU instructions at runtime from the JIT engine(s), and different styles of webpages could cause every possible combination of instructions to appear throughout the day on every machine.
