With this patch applied I did not see the WARN trigger. I booted the board without using NFS and then started used dhclient to bring up the network interface and it appears to be working fine. I can even mount the NFS share fine. So it does appear to be particular to using NFS to mount the rootfs. Cheers Jon -- nvpublic
