I remember having this kind of message on a GENERIC kernel because two
drivers were competing for the same interrupt. I would suggest that you
disable any driver besides ehci, then successively turn them on, so that
you could maybe locate which one conflicts.
On my Compaq laptop, I had to force the PCI BAR of the ehci
controler to another address than its default one, because it conflicted
with the AGP aperture !
