The below are all conditions that happen when the EDID is bad. I'm not
sure that really qualifies as "normal".

From a quick look through the code we don't always trigger an error from
the below failure paths at higher levels, so decreasing the level here
has the potential to let this kind of exceptional condition go
unnoticed.
