In this case, fw-core's bus management work and fw-sbp2's login and SCSI probe work are scheduled in parallel (in the globally shared workqueue and in fw-sbp2's workqueue, respectively). The bus reset from fw-core may then disturb and extremely delay the login and SCSI probe because the latter fails with several command timeouts and retries and has to be retried from scratch. We avoid this particular situation of sbp2_login() and fw_card_bm_work() running in parallel by delaying the first sbp2_login() a little bit. This is meant to be a short-term fix for https://bugzilla.redhat.com/show_bug.cgi?id=466679. In the long run, the SCSI probe, i.e. fw-sbp2's call of __scsi_add_device(), should be parallelized with sbp2_reconnect(). Problem reported and fix tested and confirmed by Alex Kanavin.

It has an AHCI mode and so far works correctly with board_ahci. This chip is found on Promise's FastTrak TX2650 (2 port) and TX4650 (4 port) software-based RAID cards (for which there is a binary driver, t3sas) and can be found on some motherboards, for example the MSI K9A2 Platinum, which calls the chip a Promise T3 controller. Although this controller also supports SAS devices, its default bootup mode is AHCI and the binary driver has to do some magic to get the chip into the appropriate mode to drive SAS disks. Seeing as no documentation is provided by Promise, adding this entry to the ahci driver allows the controller to be useful to people as a SATA controller (with no ill effects on the system if a SAS disk is connected - probing of the port just times out with "link online but device misclassified"), without having to resort to using the binary driver. Users who require SAS or the proprietary software raid can get this functionality using the binary driver.
