Hello,
I had a very similar problem with a bunch of supermicro boards (X6DVL-EG2).
The problem was that the bios somehow confused libata so badly that it fell
back to using the old ide legacy whatever thingy (resulting in hda instead of
sda and of course no dma).
The solution was to fiddle with the sata settings in bios. Strangely enough,
enabling mixed mode (pata and sata) in bios resulted in something the kernel
could understand and libata has been happy ever since (reporting combined
mode operation in dmesg).
good luck,
Peter
