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 ?

I think the messages that happened before those above are the important ones, and you did not show those messages here. Cheers -- Mark Lord Real-Time Remedies Inc. mlord@pobox.com
