Hi Alexey, 2010/1/26 Alexey Lobanov <A.Lobanov@xxxxxxxxxxxx>: > Hello Jeff, > hello all. > > I just report that the fresh change in vt6421_set_dma_mode does not solve > (for me) the stable problem described at http://lkml.org/lkml/2009/10/11/36 > "Lots of 6421 setups do not work".

NB: the patch had been applied to 2.6.32-rc5 instead of > Linux-next. > The change you refer to only affects the PATA-part of the vt6421, and you're trouble seems to be with the SATA port. Unfortunately, I don't have a spare SATA-disk lying around otherwise I could do some testing and perhaps be of some help.
