Add a new category for device models to log guest behaviour which is likely to be a guest bug of some kind (accessing nonexistent registers, reading 32 bit wide registers with a byte access, etc). Making this its own log category allows those who care (mostly guest OS authors) to see the complaints without bothering most users.
