Hi Tejun, According to Intel Lewisburg PCH EDS, SATA RAID controller has two types of DIDs: RSTe RAID and 3rd Party RAID. RSTe RAID shoud be drived by AHCI driver and used to construct MDRAID. These 3rd Party RAID IDs are reserved for other 3rd Party RAID drivers for variety. So, I think it's a bug to let AHCI driver supporting 3rd Party RAID IDs. And it should be ok to remove these existed device IDs. Thanks, Ocean.

Hi Ocean, no, all AHCI devices should be driven by the Linux kernel driver. We do not offer support for '3rd party' drivers in Linux.

We have already had this discussion before. I'm surprised it has come back again, this time via Intel. If Lenovo wants their RAID supported in Linux then contribute it open source to the kernel. You've been told this clearly before. Alan
