If you're big enough you can get direct access to Nvidia engineers, and they are usually transparent when they find out the bug was in their software and send you a patched version to try to resolve the issue

And when the bug is in hardware instead, good luck getting them to admit it. Instead they go "We can't confirm that there's an issue, but it'll be gone in the next revision and meanwhile don't use that instruction sequence".

That is largely what drivers do: work around hardware bugs. It's the industry's dirty secret.

To be fair: the hardware is enormously complex, and the drivers much less so.
