Ok, it's real strange now. It seems you get that machine check on
the first access to the second controller while the first works fine,
though both appear to be configured properly on the PCI bus. It
looks like the second controller isn't responding on the MMIO
addresses... Can you try my devel tree with the updated driver ?
(just in case it changes anything....) I see no reason for this
problem right now though...
