SSH, maybe? > I added debug statements in rndis_add_hdr and rndis_rm_hdr to view the packet data. As sated earlier, the packet data looks good when pinging from the device to XP. When pinging from XP to our device, the incoming packet looks OK, but there is no outgoing response. I will try to trace this through the gadget eth driver now.
Also, telnet fails form the device to the XP machine. : ( > I'm curious why you have disabled dma.

I have been using the kernel from ppc.bkbits.net/linuxppc-2.5 and lately form source.mvista.com/linux-2.5-ocp (4xx OCP support). The DMA issue was discussed at length on the ppc dev list, so I need to sort through the postings.
