Hello, Forcing the VIA Velocity interface to 1000 Mbps FDX appears to help a bit but still the connection stops transferring data after a while. I added some printk's and in or after velocity_tx_service it ends. Where should I focus with my debug printk's? It appears I can reproduce the issue by running a `find /` over ssh to the box. So perhaps it is an interrupt related issue? Please help find the root cause.
