As has been mentioned elsewhere, mdadm only recognised IMSM arrays on machines with IMSM hardware. I'm not entirely happy about this and may well change it.I have trouble answering the "least surprise" question in this area. Is it more surprising to go into your BIOS, explicitly turn off raid support and still see raid devices showing up?Is the "RAID support has been explicitly turned off" state visible from a running kernel? or is it indistinguishable from "platform does not have RAID support"?
you can try guessing, intel controllers change their pci product_id based on the mode they are set to operate in bios.
