We're trying to reproduce the original issue in the hopes of biesecting, but
have not yet discovered the secret sauce. A few questions:

- Are there any known hardware requirements, e.g. specific flavor of GPU?

- What's the average time to failure when running FurMark/PassMark? E.g.
what's a reasonable time to wait before rebooting to rerun the tests (I
assume this is what you meant when you said you sometimes needed to
reboot to observe failure).

Thanks!
