2011/4/2 arnaud atoch<arnaud.atoch@xxxxxxxxx>Bonjour, Thank you for your time devoted to maintaining the AHCI sata part of the Linux kernel. I'd like to to ask you to add the Marvell sata device found on various ASUS motherboard like mine : P5WDG2WS Pro. This sata device is listed as : 02:00.0 0106: 11ab:6141 (rev 01) 02:00.0 SATA controller: Marvell Technology Group Ltd. 88SE614x SATA II PCI-E controller (rev 01) (prog-if 81) Subsystem: ASUSTeK Computer Inc.

Could you please add this device to the list of managed devices in ahci.c ?
Have you tested a recent kernel with this device? It looks like it should have the proper class code so the AHCI driver can load without that specific device ID. Adding specific device IDs should only be needed for devices that don't do this (like those that identify as RAID or legacy IDE classes).
