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.

Best regards,

Thomas
