Rev.9 == "C0" in Marvell terminology, and that's the latest/final rev for the 6081 chip, with most of the PCI-X bugs fixed or worked around. So not much to go on there. The Bus error report was real, though. But with 3.0gb/sec sata connections, the chip will be using some different internal clocks and timings, which could be enough to avoid triggering the PCI errors. I guess. Let's hope so, anyway.
