No, that just explains the symptom of the bug, not the underlying bug, how it came about, and how they can prevent it from happening again.

"More technically, inference kernels produced incorrect results when used in certain GPU configurations" has zero technical detail. The only information it is providing us is that the bug only showed up in some GPU configurations.

I feel that it does have relevant technical detail - as far as I understand, any inference kernel is "supposed to" give the same outputs anyways, so if it produces incorrect results in certain GPU configurations, that indicates some flaw in the GPU/microcode/driver in some new hardware they introduced.
