Given the popularity of the Marvell chips, I think it's worth investigating where the problem really is and ensuring Linux works reliably with these controllers as well. > If I were seeing this problem, and I had a spare PCIe slot, then I'd > swap out the Marvell based controller for either 2x Silicon Image 3132 > based cards, or alternatively 2x Asmedia 1061 (e.g. SY-PEX40039), to see > if the problems go away. Cannot do that. I have no PCIe slots left.
