SubjectRe: [PATCH 02/15] ATA : vortex86 : fix vortex86dx/sx hardware CRC bug.
From
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.
