Booting with root-fs via NFS doesn't work with this card in slot 0. In slot 1 it works. I just tested this patch and the Linux patch you posted and the issue is still there: eth0: Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Looking up port of RPC 100005/1 on 10.0.0.152 VFS: Mounted root (nfs filesystem).
