Dear Mark,
Sorry for the incorrect mail format, so i resent it again.
Here has a problem when we put the 7042 on the kirkwood
platform(6281). When system starting to build software raid 5,
sometimes it would meet the unable to stop eDMA problem in all
channels. And then whole system is being hang ... All the phy mode
value are also not correctly if we read it out at that time.
..
Are you using a discrete 7042 chip on a PCIe bus
along with a 6281 chip ??
Or are you simply using the built-in SATA controller inside the 6281 ?
In either event, Marvell did not deem to share *any* technical info
about the 6281 with me, so I really cannot help you.
Saeed Bishara from Marvell did everything to do with that chip.
Could you please kindly have a look at the error messages and give
some advice for me to find out the root cause ? Thanks.
Thanks again.

I think the messages that happened before those above are the important ones,
and you did not show those messages here.
