Thanks a lot for fixing this. With this patch, beagleboard is able to boot into an NFS root-fs. Even when USB is used previously in U-Boot. Without this patch NFS booting hangs randomly at some time. So: Tested-by: Stefan Roese <s...@denx.de> Note: I think its a bit too late to take this patch into this release. So I suggest to apply it in the next merge-window.
