- When they do that sort of testing they test everything on the chip. Perhaps
- he got a chip where most of it works OK at 25MHz, but some less-frequently
- used instructions sometimes fail. It would seem to work, maybe a guru every
- few days, which isn't that unusual, or an occasional corrupted file.

- It might seem to work OK, but would you want to trust it for anything important?
