I don't remember in detail what your SATA problem was, but just to let you know that we are currently debugging a problem that occurs on Armada XP (more than one core is needed for the problem to occur), with SATA (the symptom is that after some time of SATA usage, SATA traffic is stalled, and no SATA interrupts are generated anymore). We're still working on this one, and trying to figure out where the problem is.
