It does not look like this issue is common - googling for "Linux EDD Boot hang" does not bring up relevant and recent results - in fact this post of yours comes on top. Further more there does not seem to be problems with newer BIOSes so we would be irritating lot many users needlessly.
Adding 3 printks for each such obscure problem would make it even more complex to parse and make sense of the boot log - I, for example, already dislike the mostly-useless-to-end-user stuff it spews on a normal boot.
If there are known chipsets / BIOSes that have this problem - applying quirks - something like this quirk for pmtmr [1]- (if they work this early) or even special casing them with forced edd=off may be the right and more useful thing to do.
