[jeffy]

>I am working on a custom board based on XPC8245LZU333B, 2 ethernet
>adapters (DP83816) were used on the PCI bus. Of cause with Linux. The

>the duration from the start of the transfer to the Linux crash maybe
>some dozens of minutes or hours. My Linux port from mvista 2.4.26
>sandpoint. I noticed that XPC8245LZU333B's PCI host can't support
>Type 2 Fast back-to-back transactions, but I am not sure if this
