MV88SX6041 > 4-port SATA II PCI-X Controller (rev 03) I have a 6081 (Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (rev 09)), it works fine under 2.6.15-rc5. No hotplug, and a few wierd problems here and there. I'm getting ~55 MB/s/disk off each of 4 disks. 220 MB/s total read. It slows way down when you start writing to them too, of course. -- Sebastian Kuzminsky
