Hi, Despite not liking what Intel did, there isn't any reason Linux shouldn't support these devices in RAID mode.. The main support issues with our Linux based product is now this problem with no hard drives listed in Linux. Get a couple everyday. Some people can't change to AHCI mode, such as some Lenovo machines. If the patch simply adds support for this mode without affecting anything when not in that mode then why wouldn't you mainline it? This problem is widespread. TIA!
