Hi, Ok, the issue I have is the following: I have connected a SATA Port Multiplier to AD-483000. And I have two sata drives connected to the Sata port multiplier (one at port 0 and second at port 1) My Linux Kernel is 2.6.24.3. I am using the drivers in the kernel.. aic94xx and libsas The drive at port 0 of the sata port multiplier is detected nicely. The problem is that the second drive on the port multiplier is not detected. After investigations.. I figured out that no one is trying to do sata port multiplier initialisation and detection. After reading the sata spec etc., I tried to modify libsas so that before detecting any sata device, it would send out FIS (soft reset ) to sata port 15 with SRST bit set to 1 followed by another FIS to sata port 15 with SRST bit set to 0. The first FIS goes out. I can see it on a SATA analyzer. The second FIS never goes out... Adaptec's driver.. is giving errors for the first FIS.
