Outlier? I would say uncommon but not an outlier. Here's a non-exhaustive list. http://wiki.osdev.org/CPU_Bugs

There was also an issue with transaction memory with both Haswel & Broadwell. The fix was to disable TSX support via micro code update. I wouldn't call disabling a fix personally. I doubt Intel even compensated the folks who bought it for the TSX support.

Yeah, that list is far from exhaustive. Years and years ago, Google's websearch cluster validation suite found a tricky bug that isn't on that list. The exchange with the CPU manufacturer was amusing.

Given how many Intel/AMD/etc. CPU releases there have been, I would still refer to such glaring implementation bugs as outliers.
