__iounmap: bad address c00f0000 <-why?

I have no idea what is causing this. If it still occurs with recent
kernels then stick a WARN_ON(1) into __iounmap()'s error path, to get a
stack dump? It is almost certainly not related to -RT.
There was a thread a few weeks ago about this same message (afaik).
The answer then was something like "the __iounmap() call is happening
very early, before the unmap machinery (data/structs) have been
set up for it." (but I don't know that first-hand, just repeating
close to what I read.)
