How did this get past validation at Intel?

This is worse than https://en.wikipedia.org/wiki/Pentium_FDIV_bug

There's another blog post going into more depth about the issue here: https://fgiesen.wordpress.com/2025/05/21/oodle-2-9-14-and-in... where they speculate that it seems to relate to both other clock-related instability on specific Raptor Lake parts and possibly the overarching voltage control problems that the platform had early on; I can't tell entirely from the bug reports whether the behavior reliably reproduces on 100% of Raptor Lakes but the indicators I'm reading point to that it doesn't. It is concerning that Intel didn't get back to Mozilla about it though, since it's certainly a lot more than a one off.

"validation? what validation?"
