I noticed thanks to DWC_PARAMS that burst size is hardcoded to 32
items on this board, however registers for SATA program it to 64. I
remember that I got no interrupt when I programmed transfer width
wrongly (64 bits against 32 bits) when I ported dw_dmac to be used
on
Intel SoCs.
One more thing, I have a patch to monitor DMA IO, we may check what
exactly the values are written / read  in DMA. I can share it
tomorrow.
As promised the patch I have to debug IO of DW DMA. Didn't check though
if it applies cleanly on top of recent vanilla kernel.
So, the original driver (with patch from Måns) works, right?

The hard drive is recognized .
These system gets unresponsive with USB devices like the mouse and
keyboard not responding  when I start Gparted.
Did you disable the SATA and DMA debug messages?

It is working.
That's good news.  Thanks a lot for helping to test this.

No problem.
If you can influence anyone of the radeon guys to have a look at the ring test failure on the Sam460ex again,
I will  be happy to help test in that area as well .
