Intel controllers after ICH6 change both ID and set of resources, depending on AHCI enabled in BIOS. There is separate set of IDs for controllers with AHCI enabled. As I can see, Linux handles ID 0x27c4 as non-AHCI SATA. If for some reason this ID could be used for both modes (I have doubts), we may try to set AHCI_Q_NOFORCE flag to make driver check PCI class/subclass, if it is correct there. -- Alexander MotinReceived on Sun Apr 18 2010 - 03:57:36 UTC
