Dear Tejun Heo, This is HighPoint Linux Team. We found Linux AHCI driver since kernel 3.16 has added ID (0x06421103) to support RocketRAID 642L which is not what we expected. If we want to load HighPoint RR642L RAID version Linux SCSI driver, it becomes conflict each other. This affects our customers who need to use our RAID version driver stack. Hence, this is to ask Linux how to solve this conflict with AHCI driver? and why Linux wants to add RR642L ID (0x06421103) into AHCI driver? Is there any way to prevent this in the future?
