I found two different versions of the Vortex86DX one with RDC_D1011 and the other RDC_D1012. I tested the RDC_D1012 with the pata_rdc driver with MWDMA2 turned on and this is the error I received. the actual error is near the bottom of the dmesg. I am pretty certain that I received the same error when I used a RDC_D1011 with the ite_821x driver with MWDMA2 turned on. I no longer have access to a Vortex86DX with the RDC_D1011.
